This blog post will teach you how to convert an int to a string in C. The itoa() function (non-standard function) converts an integer value to a null-terminated string using the specified base (behavior depends
In scenarios where an integer or a floating-point number needs to be appended to a string, thestd::to_stringfunction 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 longs...
