how do you turn a char into a string with a length of one?

[hanst99]

You can't. You can construct a string of length one from a char though - depending on what kind of string you mean.

char c = 'a';
char  str1[] = {c,'\0'}; //c string
std::string str2(1, c); //c++ string

These also work:

C++

char c = 'A';

// assignment method
string s;
s = c;

// construction method
string s = c;

C

char c = 'A';

/* assignment method 1 (works once) */
char a[ 2 ] = { 0 };
strncpy( a, &c, 1 );

/* assignment method 2 (works any number of times) */
char a[ 2 ];
strncpy( a, &c, 1 )[ 1 ] = 0;

/* construction method (C99 only)*/
char a[] = { c };

Hope this helps.
