Thread: ISO C++ forbids converting a string constant to ‘char*’

still trying to figure out how to get a char * pass back out of a function( prams )
while this works perfectly in C it does not in C++, but I need to do this very same thing in C++.

Code:

#include <stdio.h>

void watchThis ( char ** point) {
    *point = "passing a char *  results back \n"
    "through the prams\n";
}

int main (void)
{
 char * point;
 watchThis(&point);
 printf("%s\n", point);
return 0;
}

now what is the best next thing?

Yeah, make it const.

    *point = "passing a char *  results back \n"
    "through the prams\n";
}
 
int main (void)
{
 const char * point;
 watchThis(&point);
 printf("%s\n", point);
return 0;
}

that is just too simple, let me give that a try.

that was all I needed, thanks

uhg pointers and passing thru funcion prams.

I put it in here too because my functions now work in c and c++
