I need a little help with my code

[Nii Tycoon]

Hi everybody,am designing a simple calculator as a mini-project,but am encountering a whole lot of errors when i run my code using devc++. Pls help me out. Counting on your cooperation. Thank you all

#include<iostream>
#include<string>
using namespace std;
float mult(float num1,float num2);
float add(float num1,float num2);
float sub(float num1,float num2);
float divide(float num1,float num2);
int main()
{
    int choice;
    float num1,num2;
    cout<<"---------------------------------------------"<<endl;
    cout<<"---------------------------------------------"<<endl;
    cout<<"  ---------Nii's CALCULATOR!!!!!-----"<<endl;
    cout<<"---------------------------------------------"<<endl;
    cout<<"---------------------------------------------"<<endl;
    cout<<"	Make a selection:"<<endl;
    cout<<"	1.Division"<<endl;
    cout<<"	2.Adding"<<endl;
    cout<<"	3.Subtraction"<<endl;
    cout<<"	4.multiplication"<<endl;
    cout<<
cout<<"";YOUR CHOICE IS:;
    cin>>choice;
    switch(choice){
                   case 1:
                        cout<<Please enter the two numbers you want to
divide, divisor first!: ;
                        cin>>num1>> num2;
                        cin.ignore();

Hey, please edit your post to use code tags - http://www.cplusplus.com/articles/jEywvCM9/

Also, what errors are you getting?

Edit : For example, you cant have it like this -

cout<<"Please enter the two numbers 
you
want to add: ";

It all gotta be in one row - cout << "Please enter the two numbers you want to add : ";

Also lines 33, 43, 54 etc are pretty strange, you are basically outputting the string literal "<< num1<<", the placement of your speech marks is all over the place on those.

For example:

cout<<
"<<num1<<"/"<<num2<<"=<<divide(num1,num2)<<endl;

should be

cout << num1 << "/" << num2 << "=" << divide(num1,num2) << endl;
