Answer 1

#include "stdio.h"
int main ()
{
int i,j;
printf("%4C",'*');
for(i=1;i<10;i++)
printf("%4d",i);
for(i=1;i<10;i++)
{
printf("\n%4d",i);
for(j=1;j<=i;j++)
printf("%4d",i*j);
}
printf("\n");
getch();
}

Answer 2

#include <stdio.h>

int main(void) {

putchar('*');
for (int i = 1; i <= 9; i++)
printf("%4d", i);
putchar('\n');

for (int i = 1; i <= 9; i++) {
printf("%d", i);
for (int j = 1; j <= i; j++)
printf("%4d", i * j);
putchar('\n');
}

return 0;
