Program to reverse a string without using strlen()

#include<stdio.h>
#include<string.h>
void ustrrev(char*);
int main()
{
   char sstr[20] = "WebEncyclop";
   ustrrev(sstr);
}
void ustrrev(char*s)
{
    char temp[10];
    int j=0;
    int i=strlen(s)-1;
    while(i >= 0)
    {
        temp[j] = s[i];
        j--;
        i--;
    }
    temp[j] = '\0';
    printf("reverse string is %s",temp);
}

#include<stdio.h>

#include<string.h>

void ustrrev(char*);

int main()

{

char sstr[20] = "WebEncyclop";

ustrrev(sstr);

}

void ustrrev(char*s)

{

char temp[10];

int j=0;

int i=strlen(s)-1;

while(i >= 0)

{

temp[j] = s[i];

j--;

i--;

}

temp[j] = '\0';

printf("reverse string is %s",temp);

}

Output
