How do you Write a program in c to calculate the sum of two integers?

Answer 1

/*use "c-free" compiler*/

#include <stdio.h>

main()

{

int a,b,c;

printf("enter the value of a & b");

scanf("%d%d",&a,&b);

c=a+b;

printf("sum of the two numbers is a+b- %d",c);

getch();

}

Answer 2

#include<stdio.h>

#include<conio.h>

main()

{

int a,b,c;

printf("enter the value of a and b");

scanf("%d%d", &a,&b);

c=a+b;

printf("sum of the two numbers is a-b-%d",c);

getch();

}

Answer 3

sum = x ^ y;

carry = x & y;

while(carry!=0)

{

x = sum;

y = carry <<1;

sum = x ^y;

carry = x &y;

}

printf("sum = %d",sum);

Answer 4

#include<iostream.h>

void main()

{

int a,b,sum;

cout<<"Enter the two nubers";

cin>>a>>b;

sum=a+b;

cout<<"The sum is "<<sum;

return 0;

}
