Problem when running simple c program
 

#include<stdio.h>
int main()
{
printf( "I am alive! Beware.\n" );
}

Did "gcc -c smpl.c " -- compiled successfully

then did "gcc -o smpl.o " -- returning gcc: no input files

even tried "gcc -o smpl " -- returning gcc: no input files

Can any one pls tell me how to make this run successfully..

I think what you want is
gcc smpl.c -o smpl

Beware indeed.
