The code i have written down:

#include<stdio.h>
#include<stdlib.h>


void get()
{
    int i,a[50],limit;
    printf("enter the limit:");
    scanf("%d",&limit); 
    
    printf("enter the array");
    for(i=0;i<limit;i  )
    {
        scanf("%d",&a[i]);
    }
    
}

void display()
{
    int i,a[50],limit;
    printf("the array is");
    for(i=0;i<limit;i  )
    {
        printf("%d\t",a[i]);
    }

}

int main(void)
{
   int i,a[50],limit;
   get(); 
   display(); 
   
}

Output:

CodePudding user response：

When you declare int i,a[50],limit; in each of your functions, these variables are local to the functions.

For example the limit variable declared in get is totally unrelated to the limit variable declared in set etc. They just happen to have the same name.

You ether need to declare these variables as global variables (poor design), or redesign your code differently, for example by passing those variables as parameters.

All this is explained in the first chapters of your beginner's C text book.

Example using global variables (poor design)

#include <stdio.h>
#include <stdlib.h>

int i, a[50], limit;   // global variables visible
                       // from all functions

void get()
{
  printf("enter the limit:");
  scanf("%d", &limit);

  printf("enter the array");
  for (i = 0; i < limit; i  )
  {
    scanf("%d", &a[i]);
  }
}

void display()
{
  printf("the array is");
  for (i = 0; i < limit; i  )
  {
    printf("%d\t", a[i]);
  }
}

int main(void)
{
  get();
  display();
}
