C - Recursive Section Heading Code

#include <stdio.h>
#include <string.h>
void sections (int width, int depth) {
    char buf[100];
    int i;
    //sprintf(buf,"%s %s", word1, word2);
    for (i=1; i<=depth; ++i){
        printf("Section %d\n", i);
        if ( width >= 1 ){
            sections (width-1,depth-1);
                printf("    Section %d.X\n", i);
        }
    }
}

int main() {
    sections(3,3);
}

I am trying to create a program (Recursively) that will take two inputs width and depth

So depth is how many sections 'deep' you go. So a depth of one is the printing of Section 1 and similar levels (2, 3, 4, etc). Depth of 2 is Section 1.A and the similar levels (1.B, 1.C, etc). Width is how many of each you have. So width of 3 you go down 1, 2, 3. If you had a depth of 2 it would go down to the 1.A level.

for example

Section 1

   Section 1.A

      Section 1.A.1

      Section 1.A.2

   Section 1.B

      Section 1.B.1

      Section 1.B.2

Section 2

   Section 2.A

      Section 2.A.1

      Section 2.A.2

   Section 2.B

      Section 2.B.1

      Section 2.B.2

But Im trying to create a program that prints things such that :

Section 1
   Section XX
   Section XX
Section 2
   Section XX
   Section XX

I am terrible with recursion, and I have tried for hours to create this program. Thanks for any help!
