i have a code like this:
int i = 123;
char myString[100];
strcpy(myString, "my text");
and how i want to add the 123 after "my text". how to do this in c/c++?
at the end myString
sould be my test123
In C++:
std::stringstream ss;
ss << "my text" << i;
std::string resultingString = ss.str();
There's no such thing as C/C++ .
在C ++ 11中:
std::string result = "my text" + std::to_string(i);
(To complement Luchian's answer)
In C:
char myString[128];
int i = 123;
snprintf(myString, sizeof(myString), "My Text %d", i);
假设mystring足够大,在这个例子中就是这样:
sprintf( myString, "my text%d", 123 );
使用C ++中的Qt QString对象:
std::cout << QString("my text %1").arg(123456);
