Question

In C++,

Write a function that receives a string of characters and return true if the string is in language, otherwise it returns false. You may use following function header (Assume a string is in language if it is read from the left side is the same as it is read from the right side. For example, a-b-d-c is not in the language, a-b-c-a-c-b-a is in language):

bool isInLanguage_2(string aString)

And I also, want to know if my if statement is incorrect, and if it is how is it incorrect?

ebool isInlanguage_2(string string_input){
// Checking for the length and the $ sign!
if (!(string_input.Length() % 2)){
return false;
Stack<char> charStack;
for (int i = 0; i< string_input.Length(); i++){
charStack.push(string_input[i]);
}
int temp_2 = 0;
while (string_input[temp_2] != '\@'){
if (string_input[temp_2]
charStack.peek()){
==
charStack.pop();
temp_2++;
else
return false;
return true;

Expert Solution

Step 1

A program is to be written in a C++ language.
The program can be compiled on any one of the online compilers.
According to the program if the string entered is in the language then true is to be returned else false is returned.
In the below program 0 is returned if it is not in a language that is false.
If it is language 1 is returned, which is true according to the boolean.
