- A)
Explanation of Solution
Purpose of the given code:
The purpose of the given code is to divide the user input value by 2 and store the result on the variable “half”, which is declared as double.
Syntax error:
An error which occurs on the source code of a
- If the code fails to prove its language syntax format, then the compiler will throw errors.
List of errors identified in the given code:
The code that is given contains some errors and those are listed as follows:
Error 1:
The definitions of the keywords are being defined in the header file.
In “Line 1”, delete the semicolon (;) at the end of the header file “#include<iostream>”.
Error 2:
The main method is important to start the program. So, in “Line 3” must contain the datatype “int” before the term “main” and it should by brackets “()”.
Error 3:
Every line in “C++” must be terminated using a semicolon “;”.
In “Line 7” and “Line 8”, the output statement is not terminated with a semicolon“;”.
Error statement:
cout << "Enter a number and I will divide it.\n"
cout << "in half for you.\n"
Corrected statement:
cout << "Enter a number and I will divide it.\n";
cout << "in half for you.\n";
Error 4:
In “Line 9”, the variable “number1” is not declared in the given code...
- B)
Explanation of Solution
Purpose of the given code:
The purpose of the given code is to read the user name and display it on the screen. Finally, the program will get the user response by pressing the enter key as an input.
Syntax error:
An error which occurs on the source code of a program is referred as “syntax error” because the computer programs strictly follow the syntax rules.
- If the code fails to prove its language syntax format, then the compiler will throw errors.
List of errors identified in the given code:
The code that is given contains some errors and those are listed as follows:
Error 1:
The definitions of the keywords are being defined in the header file.
In “Line 1”, delete the semicolon (;) at the end of the header file “#include<iostream>”.
Error 2:
The datatype “char” is used to store a single character value. It is not used to read a string value. Hence include the “# include<string>” file in the program.
Corrected statement:
string name,go;
Error 3:
In line 9, remove the getline() function and use the normal cin statement to read the string type value...
