please help me in c

[jatinder]

I am stuck i don't know what to do can anyone please help me on this project i have to do this if i type a expresstion it should give me the answer like this 2+3/3*4+2 and it should give me 8.
And u can also type in spaces when u r writing the expresstion and it should not see the spaces. And u have to use stacks and NO pointers. PUSH AND POP

[Prelude]

An array can be used as a stack very simply:

#include <stdio.h>

int main ( void )
{
  int stack[100];
  int i, n = 0;

  /* Push four values */
  for ( i = 1; i < 5; i++ )
    stack[n++] = i;

  /* Pop all values */
  while ( n > 0 )
    printf ( "%d\n", stack[--n] );

  return 0;
}

Now you should have no problem placing those operations in separate functions and performing the appropriate calculations when you pop.
