1. A collection of various data types may be represented by which of the following ?

File

File

17.96%

Structure

Structure

55.4%

Array

Array

22.22%

String

String

4.41%

The answer will be Structure as it gives us the functionality to hold various types of data types as one.

One example of structure can be –

Struct PrepInsta {

int numberOfUsers;

char name[10];

char moto[50];

}

2. When we look at a String.h library import then, which of the following inbuilt function of library is not imported?

strptr

strptr

44.82%

strlen

strlen

15.22%

strcpy

strcpy

9.87%

strupr

strupr

30.1%

All the above functions strcpy will copy a string and upr will convert to uppercase and len with give int value of length, but ptr is not imported in String library function and is the solution.

3. Which of the following correct defines a recursive property in a programming language?

function calls another function repeatedly

function calls another function repeatedly

11.58%

function calls itself repeatedly

function calls itself repeatedly

80.88%

infinite looping of a process

infinite looping of a process

5.51%

hopping between different functions

hopping between different functions

2.02%

Answer will be B as recursion is basically a function(x) will call itself again and again the arguments passed in the function however may be variable.

4. Consider we are importing math.h function which of the following may also work without importing math.h while writing the program sinh, rand, pow, sqrt?

Only a and c

Only a and c

11.07%

none

none

33.6%

only b and c

only b and c

15.49%

only b

only b

39.84%

The answer will be D, all of the others need to import but we can use rand() without importing the math.h it basically generates a random number. It may be used will writing code for a game like Ludo, where you may need dice values as random values.

A dynamically allocated array of 550 numbers.

32.58%

Answer :: (C)

EXPLANATION :

As we our area of interest is only the 50 numbers so take An array of 50 numbers where A[0] corresponds to 51...A[49] corresponds to 100 then after reading an input just increment the counter in correct position as said above.
