c program to reverse a string using function and pointer | pointer examples in c | program with pointer to character function

 

Pointer and string programs in C

 // program to reverse a string using function where we use pointer to character

//WAP to reverse a string using(strrev()) function.Pass string as parameter and return its reverse

#include <stdio.h>

#include<string.h>

#include<conio.h>

char *stringrev(char string[]);

/* function named stringrev() that accepts a string and returns

a char(i.e. pointer to character/string)

int main()

{

    char name[100];//string declaration

    printf("enter string\n");

    scanf("%[^\n]",name); 

    printf("reverse=%s\n",stringrev(name));//prints the name

    getch();

    return 0;

}

char *stringrev(char string[])

{

    strrev(string);

    return string;
