What is the maximum value for an int32?

on

 

In C++, the maximum value for a 32-bit signed integer (int32_t) is 2147483647. This value is represented by the constant INT32_MAX, which is defined in the <limits.h> header.

Here's an example that demonstrates the maximum value for a 32-bit signed integer:

cpp
#include <iostream>
#include <limits.h>

int main() {
    int32_t maxValue = INT32_MAX;

    std::cout << "Maximum value for int32_t: " << maxValue << std::endl;

    return 0;
}

When you run this program, it will output:

arduino
Maximum value for int32_t: 2147483647

Keep in mind that the actual maximum value might vary depending on the platform and compiler you're using. However, in most common environments, a 32-bit signed integer has a maximum value of 2147483647.
