Looks like you want word to be of type std::string.
You cannot call a function before it has been declared. Either move the definitions of singleint() and singlestring() above the definition of array()

void singleint(){

}
void singlestring(){

}
void array(){
...
singleint();
...
singlestring();
...
}

Or leave the definitions where they are and just declare (without defining) singleint() and singlestring() above array().
