Explain this program step by step

Question

#include <stdio.h>

void say_hello();

int main() {
int i;

for (i = 0; i < 5; i++) {
say_hello();
}

return 0;
}

void say_hello() {
static int num_calls = 1;

printf("Hello number %d\n", num_calls);
num_calls++;

}

Answer 1

A for loop: starts at 0, ends at 4 (i < 5). i++ = i+1 (steps)
Your loop runs 5 times and calls say_hello() --> this a method/function

Whats inside your function?
There is an integer and a print statement.
num_calls = 1
print hello user and the value of num_calls
Then increment num_calls //it is now 2

For loop --> i = 0 --> jump in your method --> jump back in the for loop --> i = 1 --> jump in your method .... and so on until i = 4

You can use the code playground to see the output.

Answer 2

I got it the answer is in the function defintion for every loop it prints and increment by 1 and another loop print that value and again incremented by 1 and then used by next loop and so on
