#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
srand((size_t)time(NULL));
int x[10][10],
y[10][10],
sum[10][10],
c,
d,
i,
j;

printf("Mat X:\n");
for (c = 0; c < 10; c++)
{
for (i = 0; i < 10; i++)
{
j = rand() % 100 + 1;
x[c][i] = j;
printf("%-3d ", j);
}
printf("\n");
}
printf("\nMat Y:\n");
for (c = 0; c < 10; c++)
{
for (i = 0; i < 10; i++)
{
j = rand() % 100 + 1;
y[c][i] = j;
printf("%-3d ", j);
}
printf("\n");
}
printf("\nsum of entered matrices:\n");
for (c = 0; c < 10; c++)
{
for (d = 1; d < 10; d++)
{
sum[c][d] = x[c][d] + y[c][d];
printf("%-3d ", sum[c][d]);
}
printf("\n");
}
return 0;
}
