Question: If the user gives an even number (an invalid input), I want the program asks for the input again without running it one more time. Would you kindly help me to fix it?

An example of the output should look like this:

please enter number of rows (odd nummber): 4 please enter number of rows (odd nummber): 7 * *** ***** ******* ***** *** *

Programming c++:

#include

int main() {

int rows, i, j, k;

printf("please enter number of rows (odd nummber):");

scanf("%d", &rows);

// Ensure that the number of rows entered is odd

if (rows % 2 == 0) {

printf("please enter number of rows (odd nummber): ");

return 0;

}

// Print upper half of diamond

for (i = 1; i <= rows; i += 2) {

// Print spaces

for (j = 1; j <= (rows - i) / 2; j++) {

printf(" ");

}

// Print asterisks

for (k = 1; k <= i; k++) {

printf("*");

}

printf(" ");

}

// Print lower half of diamond

for (i = rows - 2; i >= 1; i -= 2) {

// Print spaces

for (j = 1; j <= (rows - i) / 2; j++) {

printf(" ");

}

// Print asterisks

for (k = 1; k <= i; k++) {

printf("*");

}

printf(" ");

}

return 0;

}
