Convert String to int in C++ using strtol() function (string to long integer)The strtol() method is used to convert strings to long integers. It is a function of the C standard library and can be implemented in
Int is an alias of Int32, and defines an integer number in range from -2,147,483,648 to +2,147,483,647. Setting a value of an int variable that is out of this range, will produce a “System Overflow Exception”. Converting a string to int is a common scenario. For example, we ...

String value=123, Int value=123 In this example: We include the necessary headers (<stdio.h>and<stdlib.h>). We define a stringstrcontaining the numeric characters123. We useatoi()to convertstrto an integer and store the result in thevaluevariable. ...
Take a string x as input in C-like character array format Use the sscanf() function with parameter x, the format string, and the variable address The variable value will directly be stored from the sscanf() function.ExampleOpen Compiler #include <iostream> using namespace std; int solve( ...

Hence, we must use thetoInt()function within atry-catchblock to handle the exception. With thetry-catchblock, we can assign a default print value if the exception occurs. Here’s how to incorporate thetoInt()function in thetry-catchblock. ...
