What will be the output of the program?

#include<stdio.h>
#include<stdlib.h>

int main()
{
    char *i = "55.555";
    int result1 = 10;
    float result2 = 11.111;
    result1 = result1+atoi(i);
    result2 = result2+atof(i);
    printf("%d, %f", result1, result2);
    return 0;
}

#include<stdio.h>

int main(int argc, char *argv, char *env[])
{
    int i;
    for(i=1; i<argc; i++)
        printf("%s\n", env[i]);
    return 0;
}

int proc(pf, int, int);

int main()
{
    printf("%d\n", proc(fun, 6, 6));
    return 0;
}
int fun(int a, int b)
{
   return (a==b);
}
int proc(pf p, int a, int b)
{
   return ((*p)(a, b));
}

    /* Add a statement here */
