Question

What is the output of the following code?

int w = 98;
int x = 99;
int y = 0;
int z = 1;
if (x >= 99)
{
if (x < 99)
cout << y << endl;
else
cout << z << endl;

}
else
{
if (x == 99)
cout << x << endl;
else
cout << w << endl;

}
a. 98
b. 99
c. 0
d. 1
e. None of these

Answer 1

The code checks the value of x, determines the true conditions, and outputs the value of z, which is 1.

The output of the given code is determined by the conditions within the if-else statements. The variable x is initialized with the value 99, and the first if condition checks whether x is greater than or equal to 99, which is true. It proceeds to the nested if-else, where it checks if x is less than 99, which is false. Therefore, it skips to the else statement associated with the nested if, and executes cout << z << endl;, which will output the value of z, which is 1.
