C++ Exercises: Check the upper and lower limits of integer
C++ Basic: Exercise-5 with Solution
Write a in C++ program to check the upper and lower limits of integers.
Sample Solution:
C++ Code :
#include <iostream>
#include <climits> // integer limits in header file
using namespace std;
int main()
{
cout << "\n\n Check the upper and lower limits of integer :\n";
cout << "--------------------------------------------------\n";
cout << " The maximum limit of int data type : " << INT_MAX << endl;
cout << " The minimum limit of int data type : " << INT_MIN << endl;
cout << " The maximum limit of unsigned int data type : " << UINT_MAX << endl;
cout << " The maximum limit of long long data type : " << LLONG_MAX << endl;
cout << " The minimum limit of long long data type : " << LLONG_MIN << endl;
cout << " The maximum limit of unsigned long long data type : " << ULLONG_MAX << endl;
cout << " The Bits contain in char data type : " << CHAR_BIT << endl;
cout << " The maximum limit of char data type : " << CHAR_MAX << endl;
cout << " The minimum limit of char data type : " << CHAR_MIN << endl;
cout << " The maximum limit of signed char data type : " << SCHAR_MAX << endl;
cout << " The minimum limit of signed char data type : " << SCHAR_MIN << endl;
cout << " The maximum limit of unsigned char data type : " << UCHAR_MAX << endl;
cout << " The minimum limit of short data type : " << SHRT_MIN << endl;
cout << " The maximum limit of short data type : " << SHRT_MAX << endl;
cout << " The maximum limit of unsigned short data type : " << USHRT_MAX << endl;
cout << endl;
return 0;
}
Sample Output:
Check the upper and lower limits of integer : -------------------------------------------------- The maximum limit of int data type : 2147483647 The minimum limit of int data type : -2147483648 The maximum limit of unsigned int data type : 4294967295 The maximum limit of long long data type : 9223372036854775807 The minimum limit of long long data type : -9223372036854775808 The maximum limit of unsigned long long data type : 18446744073709551615 The Bits contain in char data type : 8 The maximum limit of char data type : 127 The minimum limit of char data type : -128 The maximum limit of signed char data type : 127 The minimum limit of signed char data type : -128 The maximum limit of unsigned char data type : 255 The minimum limit of short data type : -32768 The maximum limit of short data type : 32767 The maximum limit of unsigned short data type : 65535

Why is there no std::stou?
The most pat answer would be that the C library has no corresponding "strtou", and the C++11 string functions are all just thinly veiled wrappers around the C library functions: The std::sto* functions mirror strto*, and the std::to_string functions use sprintf.
