Answer 1

Answer:

Output of C++ programs | Set 50

Predict the output of the following C++ programs:

Question 1:

#include <cstdlib>

#include <iostream>

using namespace std;

int main()

{

int ran = rand();

cout << ran << endl;

return 0;

}

Output:

1804289383

Explanation: As the declared number is an integer, It will produce the random number from 0 to RAND_MAX. The value of RAND_MAX is library-dependent but is guaranteed to be at least 32767 on any standard library implementation.

Question 2:

#include <cstdlib>

#include <iostream>

using namespace std;

int main()

{

cout << RAND_MAX << endl;

return 0;

}

Output:

2147483647

Explanation: The output is Compiler Dependent. RAND_MAX is a function used by the compiler to create a maximum random number.

Question 3:

#include <iostream>

using namespace std;

int main()

{

void a = 10, b = 10;

int c;

c = a + b;

cout << c;

return 0;

}
