Memory Leak can be defined as a situation where programmer allocates dynamic memory to the program but fails to free or delete the used memory after the completion of the code. This is harmful if daemons and servers are included in the program.
#include<stdio.h>
#include<stdlib.h>
int main()
{
int* ptr;
int n, i, sum = 0;
n = 5;
printf("Enter the number of elements: %dn", n);
ptr = (int*)malloc(n * sizeof(int));
if (ptr == NULL)
{
printf("Memory not allocated.n");
exit(0);
}
else
{
printf("Memory successfully allocated using malloc.n");
for (i = 0; i<= n; ++i)
{
ptr[i] = i + 1;
}
printf("The elements of the array are: ");
for (i = 0; i<=n; ++i)
{
printf("%d, ", ptr[i]);
}
}
return 0;
}
//Output
Enter the number of elements: 5
Memory successfully allocated using malloc.
The elements of the array are: 1, 2, 3, 4, 5,
