In scenarios where an integer or a floating-point number needs to be appended to a string, the std::to_string function comes in handy to convert the numerical value into a string before concatenation.This function can convert various numerical types, such as integers, floats, doubles, and ...
Int to string: the C-style way We can also use the C standard library functions in C++ too. One C standard library function that can do the int to string converting issnprintf(). #include <stdio.h>intsnprintf(char*str, size_t size,constchar*format, ...);The functionssnprintf() and...
