C Exercises: Show a function returning pointer

C Pointer : Exercise-15 with Solution

Write a program in C to show how a function returning pointer.

Sample Solution:

C Code:

#include <stdio.h>
int* findLarger(int*, int*);
void main()
{
 int numa=0;
 int numb=0;
 int *result;
 	printf("\n\n Pointer : Show a function returning pointer :\n"); 
	printf("--------------------------------------------------\n");
   printf(" Input the first number : ");
   scanf("%d", &numa);
   printf(" Input the second  number : ");
   scanf("%d", &numb); 	

 result=findLarger(&numa, &numb);
 printf(" The number %d is larger.  \n\n",*result);
}

int* findLarger(int *n1, int *n2)
{
 if(*n1 > *n2)
  return n1;
 else
  return n2;
}

Sample Output:

 Pointer : Show a function returning pointer :                                                                
--------------------------------------------------                                                            
 Input the first number : 5                                                                                   
 Input the second  number : 6                                                                                 
 The number 6 is larger.
