    Write a function that takes a string and returns the ROT13 version of the string; you may assume that the character set is ascii. What is the meaning of “Cebtenzzvat Cenkvf vf sha!”

    Iterate over each character in the string.
    If the character is an alphabet, add or subtract 13 from its ascii value, depending on the alphabet.
    If it's a non-alphabet, keep it as it is.

    And "Cebtenzzvat Cenkvf vf sha" translates to "programming in praxis is fun"

    P.S I can't seem to be able to post python code. When I add the code in the reply and try to post, an error message saying "Internal server error" appears.
    Without the code, it seems to be ok.

    The code could be,

    #include<stdio.h>
#include<string.h>
int main()
{
    char s[50],new[50];int len,i,temp;
    printf("Enter The String To Be Encrypted");
    gets(s);
    len=strlen(s);
    for(i=0;i<len;i++) {
        if(s[i]>64&&s[i]<91) {
            if(s[i]>77)
                s[i]=s[i]-13
            else
                s[i]=s[i]+13
        }
        else if(s>96&&s<123) {
            if(s>109)
                s[i]=s[i]-13
            else
                s[i]=s[i]+13
        }
    }
 
    printf("The ROT13 Version Of The String Is\n\n");
    printf("%s",s);
}

    Wrap it in the 'code' tags.
