Increment the first byte of a string by one

Question

I\'ve got a main program:

int main() {
    char *str = \"hello\";
    printf(\"%s\\n\", str);
    /* Shift first byte 1 to get \"iello\" */

    /*          


        

Answer 1

Do something like:

#include 
#include 

int main() {
char str[] = "hello";
printf("%s\n", str);

//str[0]=str[0]+1;

// to get uppercase letter include ctype.h header

str[0] = toupper(str[0] + 1);

printf("%s\n", str);
return 0;
}
