I have string R_20081016_*. I want to replace * with numbers in a loop. i.e. First loop * = 1 , second loop * = 2 etc. I am currently using the replace function to replace * to 1. However, I need to convert 1 to "1". How should I do this? All replies (3) Thursday,...
It is common to convert an integer (int) to a string (std::string) in C++ programs. Because of the long history of C++ which has several versions with extended libraries and supports almost all C standard library functions, there are many ways to convert an int to string in C++. This ...

First remember that getline() requires a stream and a string. You seem to be trying to use getline() with a stream and an int which won't work. You can use things like to_string() to convert a number to a string however it is usually less error prone just to store this in a st...

We can define our own iota function in c++ as: string itoa(int a) { string ss=""; //create empty string while(a) { int x=a%10; a/=10; char i='0'; i=i+x; ss=i+ss; //append new character at the front of the string! } return ss; } Don't forget to #include <stri...

After days of attempts, I am able to grasp that UInt8Array in the index.cpp file, but not able to convert it to c++ datatypes such as std::array or std::vector. For Integer type or String type, I can cast it to using ToNumber() or ToString(). But for direct conversion of ...
