Write a C program to demonstrate calloc() function.

/* C Program to demonstrate calloc() function */

#include <stdio.h>

#include <alloc.h>

#include <string.h>

int main(void)

{

/* Local definitions */

char *str NULL; /* *str is a character pointer */

str (char *) calloc(10, sizeof(char));

/* Statements */

strcpy(str, "MSSM"); /* string copy */

printf("String is %s\n", str);

free(str); /* free the memory */

return 0;

} /* main */

OUTPUT

String is MSSM

EXPLANATION: In the above program, the variable str is declared as a pointer variable. The statement ((char*)calloc(10, sizeof(char))) is assigned to pointer variable str using assignment operator. The calloc() function is used for allocating memory space. The string MSSMis copied to str using strcpy function, then prints the string and make free the pointer variable str.
