Question

Assume the following static cast int>('a') = 97 static cast int>('A') = 65 The output of the statement: cout << static_cast<int> (tolower('B')) << endl; un a. 65 b. 67 C. 96 d. 98 or

Answer 1

Hi There,

The Answer is 98.

Static cast is one of the casting methods used to convert between datatypes and classes. This consumes less time compared to dynamic cast. Static cast is efficeint in converting primitive datatypes.

In static_cast<int>(toLower('B'))

1. Lower ('B') will be executed first which will result in 'b'.

2. Ascill value of 'b' is 98 which is the value when 'b' is casted to integer.

Please comment below if you need more information.

Output:

Code:

#include <iostream>

using namespace std;

int main()
{
char ch = tolower('B');
cout << "Static cast of " << ch << " is " << static_cast<int>(ch) << endl;
cout << "static_cast<int>(tolower('B')) is " << static_cast<int>(tolower('B')) << endl;
return 0;
}
