Add Numbers :

We will write a basic C program to add two Numbers for understanding basic structure of programming. In programming , we can add n numbers easily byy using proper syntax and algorithm.

Program to add numbers

Working of Program :

In the program, we will require two numbers from user to add and some basic operators to perform the calculation.

Run 
#include<stdio.h>
int main()
{
    int a, b;
    printf("Enter first number :");
    scanf("%d",&a);
    printf("Enter second number : ");
    scanf("%d",&b);
    int add =0;
    add = a+b;
    printf("Addition of a and b is : %d", add);
    return 0;
}

Output :

Enter first number :2
Enter second number : 3
Addition of a and b is : 5

In the above program,

  • scanf will take the input from the user.
  • add variable is used to store the answer by applying the + operator
  • printf will print the output on the screen

Conditional Statement in C

Loops in C

Arrays in C

Function in C

Boolean in C

 

Example :

Let’s solve another problem by taking two decimal numbers from user.

Run 
#include<stdio.h>
int main()
{
    float a, b;
    printf("Enter first number :");
    scanf("%f",&a);
    printf("Enter second number : ");
    scanf("%f",&b);
    float add =0;
    add = a+b; 
    printf("Addition of a and b is : %f", add);
    return 0;
}

Output :

Enter first number : 5.0
5.0
Enter second number : 6.90
Addition of a and b is : 11.900000
