Let’s just try it!!!

#include<stdio.h>
int main()
{
    int a[3][3],b[3][3],c[3][3];
    for(int i = 0;i < 3;++i)
        for(int j = 0;j < 3;++j)
            c[i][j] = 0;
    printf("Enter the element of a:(3 * 3)\n");
    for(int i = 0;i < 3;++i)
        for(int j = 0;j < 3;++j)
            scanf("%d",&a[i][j]);
    printf("Stage 1:Done!!!\n");
    printf("Enter the element of b:(3 * 3)\n");
    for(int i = 0;i < 3;++i)
        for(int j = 0;j < 3;++j)
            scanf("%d",&b[i][j]);
    printf("Stage 1:Done!!!\n");
    for(int i = 0;i < 3;++i)
        for(int j = 0;j < 3;++j)
            for(int k = 0;k < 3;++k)
                c[i][j] += a[i][k] * b[k][j];
    printf("This is Matrix C:\n");
    for(int i = 0;i < 3;++i)
    {
        for(int j = 0;j < 3;++j)
            printf("%d ",c[i][j]);
        printf("\n");
    }
    return 0;
