How to concatenate a const char array and a char array pointer?

Question

Straight into business: I have code looking roughly like this:

char* assemble(int param)
{
    char* result = \"Foo\" << doSomething(param) << \"bar\         


        

Answer 1

"Foo" and "Bar" are literals, they don't have the insertion (<<) operator.

you instead need to use std::string if you want to do basic concatenation:

std::string assemble(int param)
{
    std::string s = "Foo";
    s += doSomething(param); //assumes doSomething returns char* or std::string
    s += "bar";
    return s;
}
