// Solid Rectangle (User-Defined Size)
#include <stdio.h>

int main() {
    // Step 1: Declare variables for rows and columns
    int numRows, numCols;

    // Step 2: Prompt user for input
    printf("Enter the number of rows: ");
    scanf("%d", &numRows);
    printf("Enter the number of columns: ");
    scanf("%d", &numCols);

    // Step 3: Input validation (optional but good practice)
    if (numRows <= 0 || numCols <= 0) {
        printf("Dimensions must be positive integers.\n");
        return 1; // Indicate an error
    }

    printf("\nYour rectangle:\n");

    // Step 4: Outer loop for rows

        for (int j = 0; j < numCols; j++) {
            printf("*");
        }
        printf("\n");
