Use the atoi() or atol() function.

To convert an integer array to a string array in C, you can use the sprintf function within a loop to format each integer as a string. First, create a string array with enough space to hold the string representations. Then, iterate through the integer array, using sprintf to convert each integer to a string and store it in the corresponding index of the string array. Here's a simple example: #include <stdio.h> void intArrayToStringArray(int *intArray, char stringArray[][12], int size) { for (int i = 0; i < size; i++) { sprintf(stringArray[i], "%d", intArray[i]); } }
In ASP.NET using C#, you can convert a string to an integer using the int.Parse() method or int.TryParse() method for safer conversion. For example, int number = int.Parse(yourString); will convert the string to an integer but will throw an exception if the string is not a valid integer. Alternatively, int.TryParse(yourString, out int result) returns a boolean indicating success or failure and assigns the converted integer to result if successful, avoiding exceptions.
You can perform arithmetic with it. int x {42}; x *= 2; // ok std::string s {"Hello"}; s *= 2; // error: std::string::operator*= (int) is undefined
Use an implicit or explicit cast. Since integers are whole numbers, the decimal portion will be truncated. Example in C: float f; int i; f = 1.5; i = f; // i = 1.0 Example in C++: float f = 1.5; int i = ( int ) f;
