it is my homework.. i did these program. however it is working, there are still some problems too.. for example, i can't find prime number, i can't sum series, also i can't find a sample run as question asks.
here it is...
CODE
#include <stdio.h>
int main(void)
{
int n,j;
double sum;
char ch;
do
{
printf("Enter (P)rime, (S)erie or (Q)uit:\n");
scanf("%c",&ch);
switch(ch)
{
case 'P':
printf("Enter a positive integer:\n");
scanf("%d",&n);
{
if(n%2==1)
printf("%d is not a prime number\n",n);
else
printf("%d is a prime number\n",n);
}
break;
case 'S':
printf("Enter a positive integer:\n");
scanf("%d",&n);
sum=0;
for(j=1; j<=n; j++)
{
sum=sum+(1/j);
}
printf("Sum of first %d elements:%f\n",n,sum);
break;
}
}
while(ch!='Q');
getchar();
getchar();
return(0);
}
