Linux command to print code structure


I learned this command, but I forgot what it was now... I googled it, but cannot find anything.

Let's say that I have a following code.
Code:
/* rows.c */
#include <stdio.h>
#define ROWS  6
#define CHARS 10

int main(void) {
    int row;
    char ch;

    for (row = 0; row < ROWS; row++) {
        for (ch = 'A'; ch < ('A' + CHARS); ch++) {
            printf("%c", ch);
        }
        printf("\n");
    }
    return 0;
}
From a terminal, the command I forgot will print something like following,
Code:
$ command rows.c
main {
    for {
        for {
        }
    }
}
I do not remember exact format of output. I think it prints any for-loop, while-loop, etc. It should show some kind of structure or hierarchy of the file.

Does anyone know this command?

You must compile your source code first then run the program generated.

Code:
gcc -o /path/to/myProgram  /path/to/rows.c
and

Code:
 /path/to/myProgram
