What is the Output

[Angela]

I saw a question in a C program as below:

void test (int a)
{
if (a > 0)
test(--a);
printf("%d, ", a);
}
int main()
{
test(5);
return 0;
}

I want to know how the above program is executed and the output of the above program. Kindly help me know about this.

The output of the above C program you have given is
0, 0, 1, 2, 3, 4,

This is because the value of test is passed with parameter as 5 which is initial value of 5 in test() function. This value of a gets decremented until the value of a is greater than 0 and so when a reached the value of 0 it gets printed and the logic is proceeded as such till the value reaches the value of 5.
