C Program for Addition of Two Numbers

//C Program for Addition of Two Numbers (Simple Way)

#include<stdio.h>
void main()
{
  //Declaring three Variables
     int x, y, sum;           

 //Input  Numbers
   printf("Enter Two Numbers : \n");    
   scanf("%d %d",&x, &y);     

  //Calculating Sum of Two numbers
   sum = x + y ;

//Desplaying Sum
   printf("Sum is : %d", sum);    

}

Output

Enter Two Numbers :
2
9

Sum is : 11

C Program to Find the Sum of Two Numbers Using Function

To find the sum of two numbers through a function, first you need to know about the function. You can read about the function from the link given below.

Function in C

Algorithm

Program Start
Declaring variables
Input two Number
Calling Function to calculate Sum of Two Numbers
Print the Sum of two Numbers
Program End

Program

//C Program to Find the Sum of Two Numbers Using Function

#include<stdio.h>
int sum(int, int);
int main()
{
 //Declaring Variables
   int x, y, s;

  //Input two Numbers From User
   printf("Enter Two Numbers : \n");
   scanf("%d %d",&x, &y);

 //Calling Function to find the Sum of two numbers
   s = sum(x,y);
   
  printf("Sum is : %d \n", s);

   return 0;
}
int sum(int a, int b)
{
    return (a+b);
}

Output

Enter Two Numbers :
32
81

Sum is : 113

C Program to Find the Sum of Two Numbers Using Array

To find the sum of two numbers through an Array, first you need to know about the Array. You can read about the Array from the link given below.

Array in C

Algorithm

Program Start
Declaring variables (sum , a[2])
Input two Numbers From the User
Calculating Sum
Display the Sum of two Numbers
Program End

Program

//C Program to Find the Sum of Two Numbers Using Array

#include<stdio.h>
int main()
{
  //Declaring  Variables

   int i, sum = 0, a[2];

//Input Numbers
   printf("Enter Two Numbers : \n");
   for(i=0; i<2; i++)
   {
    scanf("%d",&a[i]);
   }

//Calculating Sum
   for(i=0; i<2;i++)
   {
    sum = sum + a[i];
   }
   printf("Sum is : %d", sum);

 return 0;
}

Output

Enter Two Numbers :
23
75

Sum is : 98
