    start var at 0 or 1

    Code:
    #include <stdio.h>
      
    int i, p;
    
    
    char letter_a = 'A';
    
    
    int main (void)
    {
    
    
            for (i = 0; i < 10; ++i)
            {
                    printf("%d. ", i);  // count 1 to 10
    
    
                    for (p = 0; p < 10 - i; ++p)
                    {
                            printf("%c", letter_a); // output num_0 p times
                    }
    
    
                    printf("\n");
            }
    
    
            return 0;
    }

    Please, which line of code would I edit to adjust the executed code to display start/end lines to begin or end at 0, 1 or 9 or 10?

    Code:
            for (i = 0; i < 10; ++i)

    here this is the final program, with the format specifiers and the => operator

    Code:
    #include <stdio.h>
    
    
    char letter_a = 'A';
    
    
    int main (void)
    {
    
    
            for (int i = 1; i <= 10; ++i)
            {
                    printf("%2d. ", i);  // count 1 to 10
    
    
                    for (int p = 0; p <= 10 - i; ++p)
                    {
                            printf("%c", letter_a); // output num_0 p times
                    }
    
    
                    printf("\n");
            }
    
    
            return 0;
    }

    Enjoy...

    start/end lines to begin or end at 0, 1 or 9 or 10?
    Code:
    #include <stdio.h>
      
    int i, p;
    char letter_a = 'X';
    
    int main (void) {
    
        int start = 5, finish = 15;
    
        for (i = start; i <= finish; ++i) {
            printf( "%d. ", i ); 
            for (p = 0; p <= finish - i; ++p) {
                printf( "%c", letter_a );
            }
            printf("\n");
        }
    
        return 0;
    }
