How do I add a do-while loop in this program so that if the input is less than 4 it doesn't pri-CodePudding

#include <stdio.h>

int main () {

    int row, i, j;

    printf("Enter a number: ");
    scanf("%d", &row);

        for (i=1; i<=row; i  ) {

        for (j=1; j<=row; j  ) {

            if (i==1 || i==row || i j==row 1) {

                printf("*");
            }
            else 
            {
            printf(" ");
            }
        }
        printf("\n");
    }
    printf("\n\n");
    }
    return 0;
}

The program prints out the letter "Z" out of stars. I have to add a do-while loop in this. (This is for school, you can clearly see that I'm a begginer.)

CodePudding user response：

Perhaps this is what you want:

do {
    printf("Enter a number: ");
    scanf("%d", &row);
    if (row < 4) puts("Try again");
} while (row < 4);

CodePudding user response：

like that?

printf("Enter a number:");
do{
   scanf("%d",%row);
}while(row<4);
