Multiplication Table

#include <stdio.h>
#include <math.h>
int main(void){
    int i,j;
    i=j=1;
    while(i<=10){
     j=1;
    while( j<=10){
     printf("%d ",i*j);
    j=j+1;
    }
    printf("\n");
    i=i+1;
    }
     return 0;
}

Example: Dynamic Multiplication Table

#include <stdio.h>

int main() {
    int num, i;
    printf("Enter a number: ");
    scanf("%d", &num);

    for (i = 1; i <= 10; i++) {
        printf("%d x %d = %d\n", num, i, num * i);
    }
    return 0;
}

Example: Inverted Multiplication Table

#include <stdio.h>

int main() {
    for (int i = 10; i >= 1; i--) {
        for (int j = 10; j >= 1; j--) {
            printf("%3d ", i * j);
        }
        printf("\n");
    }
    return 0;
}

Example: Multiplication Table with Sum of Rows

#include <stdio.h>

int main() {
    for (int i = 1; i <= 10; i++) {
        int row_sum = 0;
        for (int j = 1; j <= 10; j++) {
            printf("%3d ", i * j);
            row_sum += i * j;
        }
        printf(" | Sum = %d\n", row_sum);
    }
    return 0;
}
