  1. Given code of "sum of first and last" is incomplete.
    here is the code for "sum of first and last" in C
    #include
    #include
    int main() {
    int a,b,i=10,x;
    scanf("%d%d",&a,&b);
    a=b%10;
    x=b;
    int c;
    while(i!=0) {
    b=b/10;
    if(b%10==0) {
    break;
    }
    else {
    c++;
    }
    --i;
    }
    for (i=0; i<c; i++) {
    x=x/10;
    }
    printf("\n%d",x+a);
    return 0;
    }
