What will be the output of the following C code?

#include
enum abekus
{
   a,b,c=5
};
enum abekus s;
main()
{
   c++;
   printf("%d",c);
}

#include <stdio.h>
int fun(char *str1)
{
char *str2 = str1;
while(*++str1);
return (str1-str2);
}

int main()
{
char *str = "Abekus";
printf("%d", fun(str));
return 0;
}

What is the expected output of the following program?

main()

{

int a, b = 0;

static int c[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

for (a = 0; a < 10; ++a)

if ((c[a] % 2) == 0) b += c[a];

cout << b;

}

Pick the right option.

Statement 1: Global values are not initialized by the stream.
Statement 2: Local values are implicitly initialised to 0.
