Develop a C-script which generates the above-mentioned pattern.

Answer 1

#include <stdio.h>


int main() {
    char alphabet[] = "abcdefghijklmnopqrstuvwxyz";
    int n = sizeof(alphabet) / sizeof(alphabet[0]) -  1;
    char ch;


    for (int i=0; i<n; i++) {
        ch = getc(stdin);
        for (int j=0; j<=i; j++) {
            for (int k=0; k<=j; k++) {
                fputc(alphabet[k], stdout);
            }
            fputc('\n', stdout);
        }
        fputc('\n', stdout);
    }
    return 0;
}
