Question 1.

Observe the following C++ code and find out, which out of the given options (i) to (iv) are the expected correct output. Also assign the maximum and minimum value that can be assigned to the variable 'Go'.

void main() { int <math>X [4] = \{100, 75, 10, 125\};</math> int <math>Go = random(2) + 2;</math> for (int <math>i = Go; i < 4; i ++)</math> cout<<X [i]<<"$$";

1. 100$$75
2. 75$$10$$125$$
3. 75$$10$$
4. 10$$125$

Answer:

1. is correct option Max. <math>Value = 3</math> Min. Value = 2

Question 1.

Write the difintion of a function grace_score (int score [], int size) in C ++, which should check all the elements of the array and give an increase of 5 to those scores which are less than 40.

Example: if an array of seven integers is as follows: 45,35,85,80,33,27,90 After executing the function, the array content should be changed as follows: 45,40,85,80,38,32,90

Answer:

void grace score(int score[].int size) for (int <math>i=0</math>; <math>i < size</math>; <math>i++</math>) if (score [i]<40) score [i] = score[i] + 5; cout< }

Question 2.

Find the output of the following C+ + program: #include<iostream.h> void repch(char s[]) { for(int i=0;s[i]!='\0';i++) { if(((i\%2)!=0)) &&(s[i]!=s[i + 1])) { S[i]='@'; cout<<"Hello"; } else if (s[i]==s [i + 1]) { s[i+1]="!"; i++; } } void main() { char str[]="SUCCESS"; cout<<"Original String"<<str; repch(str);</pre> cout<<"Changed String"<<str; }</pre>

Answer: Original String SUCCESS Changed String S@C!ES!

Question 3.

Find the output of the following:

#include<iostream.h> void switchover (int A[],int N, int split) for (int <math>K=0</math>; <math>K<N</math>; <math>K++</math>) if(K<split)</pre> <math display="block">A [K] + = K;</math> else A[K] *=K; } void display(int A [], int N) for (in <math>K=0</math>; <math>K<N</math>; <math>K++</math>) <math>(K%2==0)</math>? Cout<math><<A[K]<<"%"</math>: cout << A[K] << endl; void main() { int H <math>[]</math> = {30, 40, 50, 20, 10, 5}; switchover(H, 6, 3); display(H, 6);
