Look at the following C++ code and find the possible output(s) from the options (i) to (iv) following it. Also, write the highest and lowest values that can be assigned in the array A.
Note :
● Assume all the required header files are already being included in the code.
● The function random(n) generates an integer between 0 and n-1.

void main()
{
  randomize();
  int A[4], C;
  for(C=0; C<4; C++)
  A[C]=random(C+1)+10;
  for(C=3; C>=0; C--)
  cout<<A[C]<<"@";
}

Anil typed the following C++ code and during compilation he found three errors as follows:
(i) Function strlen should have prototype
(ii) Undefined symbol cout
(iii) Undefined symbol endl
On asking, his teacher told him to include necessary header files in the code. Write the names of the header files, which Anil needs to include, for successful compilation and execution of the following  code

void main()
{
  char Txt[] = "Welcome";
  for(int C= 0; C<strlen(Txt); C++)
    Txt[C] = Txt[C]+1;
    cout<<Txt<<endl;
}

Ronica Jose has started learning C++ and has typed the following program. When she compiled the following code written by her, she discovered that she needs to include some header files to successfully compile and execute it. Write the names of those header files, which are required to be included in the code.

void main()
{
  double X,Times,Result;
  cin>>X>>Times;
  Result=pow(X,Times);
  cout<<Result<<endl;
}

Observe the following program very carefully and write the names of those header file(s), which are essentially needed to compile and execute the following program successfully:

typedef char TEXT[80];
void main()
{
  TEXT Str[] = "Peace is supreme";
  int Index=0;
  while (Str[Index]!='\0')
    if (isupper(Str[Index]))
    Str[Index++]='#';
    else
  Str[Index++]='*';
  puts(str);
}

Study the following program and select the possible output(s)from the option (i) to (iv) following it. Also write the maximum and the minimum values that can be assigned to the variable NUM.
Note:

– Assume all required header files are already being includedin the program.
– random(n) function generates an integer between 0 and n-1.

void main()
{
  randomize();
  int NUM;
  NUM=random(3)+2;
  char TEXT[]=”ABCDEFGHIJK”;
  for (int I=1;I<=NUM; I++)
  {
    for (int J=NUM;J<=7;J++)
    cout<<TEXT[J];
    cout<<end1;
  }
}

Observe the following program very carefully and write the name of those header file (s), which are essentially needed to compile and execute the following program successfully:

typedef char STRING[80];
void main()
{
STRING Txt[] = “We love Peace”;
int Count=0;
while (Txt[Count]!=’\0′)
if (isalpha(Txt[Count]))
Txt[Count++]=’@’ ;
else
Txt[Count++]=’#’ ;
puts (Txt) ;
}

Study the following program and select the possible output(s) from the option (i) to (iv) following it. Also, write the maximum and the minimum values that can be assigned to the variable VAL.
Note:
– Assume all required header files are already being included inthe program.
– random(n) function generates an integer between 0 and n-1.

void main()
{
  randomize();
  int VAL;
  VAL=random(3)+2;
  char GUESS[]="ABCDEFGHIJK";
  for (int I=1;I<=VAL;I++)
  {
    for(int J=VAL;J<=7;J++)
      cout<<GUESS[J];
    cout<<endl;
  }
}

Anil typed the following C++ code and during compilation he found four errors as follows:
(i) Function strlen should have a prototype
(ii) Undefined symbol cout
(iii) Undefined symbol endl
(iv) Function getchar should have a prototype
On asking his teacher told him to include necessary header files in the code.
Write the names of the header files, which Anil needs to include, for successful compilation and execution of the following code:

void main()
{
  char S[] = "Hello";
  for(int i = 0; i<strlen(S); i++)
  S[i] = S[i]+1;
    cout<<S<<endl;
  getchar();
}

Look at the following C++ code and find the possible output(s) from the options (i) to (iv) following it. Also, write the maximum values that can be assigned to each of the variables R and C.
Note:
– Assume all the required header files are already being included in the code.
– The function random(n) generates an integer between 0 and n-1

void main()
{
  randomize();
  int R=random(3),C=random(4);
  int MAT[3][3] = {{10,20,30},{20,30,40},{30,40,50}};
  for(int I=0; I<R; I++)
  {
    for(int J=0; J<C; J++)
