What will be the output of the following program?

#include <stdio.h>
void increment(void) {
    static int count = 5;
    count++;
    printf("%d ", count);
}
int main(void) {
    increment();
    increment();
    increment();
    return 0;
}

What is the compilation result of initializing a static local variable with a non-constant automatic variable, such as 'int val = 10; static int s_val = val;'?

What are the default initial values of uninitialized automatic (auto) and global static variables in C respectively?

Why is returning the pointer to a non-static local variable from a C function unsafe?

What is the output of the following C program?

#include <stdio.h>
void fnA(void) {
    static int x = 10;
    x++;
    printf("%d ", x);
}
void fnB(void) {
    static int x = 50;
    x++;
    printf("%d ", x);
}
int main(void) {
    fnA(); fnB(); fnA(); fnB();
    return 0;
}
