What is the formula for triangles area?

The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

How do you find area in C?

# include<stdio.h> …
int main(){} It represents the main part of the programming. …
float r, Area, Perimeter; …
printf(“ Enter the radius of circle ”); …
scanf(“%f”,&r); …
Area = 3.14*r*r; …
Perimeter=2*3.14*r; …
printf(“the area of the circle is %f\n”,Area);

How do you find the area of a triangle in C++?

We will accept the height and base values from user and apply the formula of Area of triangle : (1/2)*Base*Height.

How do you program the area of a rectangle?

#include <stdio.h>
int main()
{
int width=5;
int height=10;
int area=width*height;
printf(“Area of the rectangle=%d”,area);
}

How do you find the area of a triangle with all three sides?

To calculate the area of a triangle with 3 known sides, use Heron’s Formula. …
Heron’s formula is Area = √( s(s-a)(s-b)(s-c) ), where a, b and c are the three side lengths of a triangle and s = (a + b + c) ÷ 2.

What is scanf () in C?

In the C programming language, scanf is a function that reads formatted data from stdin (i.e, the standard input stream, which is usually the keyboard, unless redirected) and then writes the results into the arguments given.

How do you write powers in C?

pow() is function to get the power of a number, but we have to use #include<math. h> in c/c++ to use that pow() function. then two numbers are passed. Example – pow(4 , 2); Then we will get the result as 4^2, which is 16.

What is array in C?

An array is defined as the collection of similar type of data items stored at contiguous memory locations. Arrays are the derived data type in C programming language which can store the primitive type of data such as int, char, double, float, etc.

What command is used to find the area of triangle?

s = (a + b + c) / 2. # calculate the area. area = (s*(s-a)*(s-b)*(s-c)) ** 0.5.

How do you find the area and perimeter of a triangle in C++?

#include<iostream> #include<math.h> using namespace std; class Triangle { public: void area(int a,int b,int c); void perimeter(int a,int b,int c); }; void Triangle::area(int a,int b,int c) { float s=((a+b+c)/2.0),A=sqrt(s*(s-a)*(s-b)*(s-c)); cout<<“Area of a triangle is: “<<A<<” sq. …

How do you find the 3rd side of a triangle?

Pythagorean Theorem for the Third Side of a Right Angle Triangle. The Pythagorean Theorem is used for finding the length of the hypotenuse of a right triangle. So, as long as you are given two lengths, you can use algebra and square roots to find the length of the missing side.

What is the algorithm for finding the area of a square?

FIRST MOVE: START/
SECOND MOVE: RECEIVE THE SQUARE SIDE/
THIRD MOVE: FOR FINDING THE AREA OF SQUARE FIND THE SIDE OF THE SQUARE/
FOURTH MOVE: SHOW AREA/SIXTH MOVE: STOP.

How do you write a program?

Understand the problem you are trying to solve.
Design a solution.
Draw a flow chart.
Write pseudo-code.
Write code.
Test and debug.
Test with real-world users.
Release program.

What does *= mean in C?

*= Multiply AND assignment operator. It multiplies the right operand with the left operand and assigns the result to the left operand.

Is Armstrong a number?

Armstrong number is a number that is equal to the sum of cubes of its digits. For example 0, 1, 153, 370, 371 and 407 are the Armstrong numbers.

How do I print double Inc?

We can print the double value using both %f and %lf format specifier because printf treats both float and double are same. So, we can use both %f and %lf to print a double value.

What is the string in c?

In C programming, a string is a sequence of characters terminated with a null character \0 . For example: char c[] = “c string”; When the compiler encounters a sequence of characters enclosed in the double quotation marks, it appends a null character \0 at the end by default.

What is void main in c?

Void main () is the entry point for execution in C program. The void is a keyword that represents function will not return anything but a void value. Main is the name of the function and () represents parameter list that can be passed to function in this case nothing is passed.

What is Stdio h in c?

stdio. h is a header file which has the necessary information to include the input/output related functions in our program. … If we want to use printf or scanf function in our program, we should include the stdio. h header file in our source code.

What is a pointer in C?

A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address.

What is stack in C?

A stack is a linear data structure, collection of items of the same type. Stack follows the Last In First Out (LIFO) fashion wherein the last element entered is the first one to be popped out. In stacks, the insertion and deletion of elements happen only at one endpoint of it.

What do you mean by pointer arithmetic in C?

Address arithmetic is also called pointer arithmetic. … Adding or subtracting from a pointer moves it by a multiple of the size of the data type it points to. For example, assume we have a pointer to an array of 4-byte integers. Incrementing this pointer will increment its value by 4 (the size of the element).

How do you find the area of a triangle with 3 sides without the height?

What is Heron’s Formula Used For? Heron’s formula is used to find the area of a triangle that has three different sides. The Heron’s formula is written as, Area = √[s(s-a)(s-b)(s-c)], where a, b and c are the sides of the triangle, and ‘s’ is the semi perimeter of the triangle.

What is the formula of Semiperimeter?

The semi perimeter of a triangle can be calculated if the length of the three sides is given. The formula for the semi perimeter of a triangle is S = (a + b + c)/2, where ‘a’, ‘b’, ‘c’ are the three sides of the triangle.
