Consider the following C program: #include<stdio.h> void fun1(char *s1, char…

Consider the following C program:

#include<stdio.h>
void fun1(char *s1, char *s2){
        char *tmp;
         tmp = s1;
        s1 = s2;
        s2 = tmp;
}

void fun2(char **s1, char **s2){
        char *tmp;
        tmp = *s1;
        *s1 = *s2;
        *s2 = tmp;
}

int main(){
        char *str1 = "Hi", *str2 = "Bye";
        fun1(str1, str2); printf("%s %s ", str1, str2);
        fun2(&str1, &str2); printf("%s %s", str1, str2);
        return 0;
}

The output of the program above is
