    A program on C language without using subtraction operator is done by taking the numbers 2's complement and then add it to another number.

    #include<stdio.h>
    
    int main(){
    
        int a,b;
        int sum;
         int complement=0;
    
        printf("Enter any two integers: ");
        scanf("%d%d",&a,&b);
         complement= ~b+1;                               //2's complement of b
    
        sum = a + b; 
    
        printf("Difference of two integers: %d",sum);
    
        return 0;
    }
    

    Sample Output:

    Enter any two integers: 7 4
    Difference of two integers: 3
