Addition of a digit to the elements of an array using pointer arithmetic, while the user defined array is passed to the called function using pointer.

#include<stdio.h>
void pass(int *);
int main(void)
{
int *array,i=0,*a;
int b=10;
array=(int*)calloc(sizeof(int)*b);
printf("Enter the %d elements of the array :: ",b);
for(i=0;i<10;i++)
{
scanf(" %d",&array[i]);
}
a=array;
pass(a);
for(i=0;i<10;i++)
{
printf("%d ",array[i]);
}
return 0;
}

A simple program to pass a string to another function using pointer and to print it from called function.

#include<stdio.h>
void pass(char *);

int main(void)
{
char *string="Subhabrata";
pass(string);
return 0;
}

void pass(char *pass)
{
int i=0;
char *t=pass;
t=pass;
for(i=0;i<10;i++)
{
printf("%c",*t++);
}
}
