Answer / m santhosh
int count=0;
int number=100; //// print Prime no's from 1 to 100
for(int i=1;i<=number;i++)
{
count=0;
for(int j=1;j<=i;j++)
{
if((i%j==0))
{
count++;
}
}
if(count<=2)
{
printf("\nPrime Number = %d",i);
}
}

Answer / aravind
#include<stdio.h?
int main()
{
int i,count=0;
for(i=1;i<=100;i++)
{
a=i%10;
if(a==0)
{
count++;
if(count<=2)
printf("the prime numbers are %d",i);
}
else
count=count;
}
the above answer is good but it will not print 1 as prime.

why return type of main is not necessary in linux
main() { int i=0; while(+(+i--)!=0) i-=i++; printf(i); }
typedef struct { int i:8; char c:9; float f:20; }st_temp; int getdata(st_temp *stptr) { stptr->i = 99; return stptr->i; } main() { st_temp local; int i; local.c = 'v'; local.i = 9; local.f = 23.65; printf(" %d %c %f",local.i,local.c,local.f); i = getdata(&local); printf("\n %d",i); getch(); } why there there is an error during compiling the above program?
