    Exclamation help a beginner

    hello
    I know that question is very simple for all of you but it's not for me
    i just need the answers
    thank you all

    1- write a program that reads 2 strings of the same length from the user and prints"same" if these strings are identical
    else it prints"different"

    2- find and correct the error

    Code:
     void fun(const int b[],int n)
    { for(int i=0,i<n,i++)cout<<++b[];}
    void main( ){ int a[5]={2,4,3,5,6}:fun{a,5);}


    Code:
     int b[9]={0,1,2,3,4,5,6,7,8,9};
    for (int i=0,i<=9.i++)b[i]=i;


    3-what will the output of the following code
    Code:
    float x[10]={5.5,6.5,7.5,8.5,9.5,12.5,14.5,16.5,18.5,20.5}
    cout <<static cast<int>(x[9/2]/2;


    4- write a program that reads the mode value of the following data elements
    Code:
    {1,1,2,2,3,5,5,9,8,7,7,5,2,75,2,2,4,4,)

    You are right to say that these questions are very simple for me. However, were I to take that little bit of time of mine to write out the answers for you to use verbatim, they will always be very hard for you, i.e., you will remain a beginner. Forever. That's all very well if you were hiring me to code for you, but these are obviously homework questions, so nope: you're trying to cheat.

    As such, no, you need to answer the questions yourself. We might be able to help you along, but you need to take effort to understand and make your best attempts.

    For starters, you need to indent the code properly, e.g.,
    Code:
    void fun(const int b[],int n)
    {
        for (int i = 0, i < n, i++)
            cout << ++b[];
    }
    
    void main()
    {
        int a[5] = {2, 4, 3, 5, 6}:
        fun{a, 5);
    }
    This will allow you to read the code more easily, and hence allow you to find the errors in the code more easily.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Take question #2: what mistakes did you spot? List all of them. Then, now that you are no longer in the exam hall, compile the program. What errors are reported by your compiler? Fix the errors that you spotted earlier and compile again. What errors are still reported by your compiler?

    Just a little boost:

    Code:
    #include <iostream>
    
    using namespace std;
    
    void fun(const int b[], int n)
    {
        for (int i = 0; i < n; i++)
        {
            cout << b[i];
        }
            
    }
    
    int main()
    {
        int a[5] = { 2, 4, 3, 5, 6 };
        fun( a, 5);
        
    }
