2. int main()
{
int i=1,n,s=0;
printf("Enter number to set range : ");
scanf("%d",&n);
printf("\nEven numbers in range 1 to %d :\n\n",n);
for(i=1;i<=n;i++)
{
if(i%2==0)
{
printf("%d ",i);
s=s+i;
}
}
printf("\n\nSum of even numbers in range 1 to %d : %d",n,s);
return 0;
}
3. #include <stdio.h>
int main() {
int n, i;
printf("Enter an integer: ");
scanf("%d", &n);
for (i = 1; i <= 10; ++i) {
printf("%d * %d = %d \n", n, i, n * i);
}
return 0;
