just a quick question here

[dinamit875]

does anyone know how to convert c program code into c++ program code? I have program written in c code, but need the same program and its functions in c++. I can post code if needed. Thanks.

[William Hemsworth]

Well, C++ can compile almost any C code, except for a few minors differences. Post the code and I'll see.

[dinamit875]

I know that c++ can compile most of c code, but i just need c++ code not c code heres the code:

#include <stdio.h>
#include <string.h>

void addTeam(char[50], int);
void calculateResult(int, int, int, int);

char newTeam[50];
int menuChoice = 0;
int numOfTeams = 0;
int team1, team2, team1Score, team2Score;

typedef struct
{
	char name[50];
	int points, goalsFor, goalsAgainst, played, won, lost, drawn;
} team;

team teams[6];

void sortTable(team[]);
  
int main(void)
{
	int i;
    while (menuChoice != 4)
	{
		printf("Football League\n\n");
		printf("1. Add team\n");
		printf("2. Display league table\n");
		printf("3. Add result\n");
		printf("4. Quit\n");
		scanf("%d", &menuChoice);	

		if (menuChoice == 1)
		{

				fgets(newTeam, sizeof(newTeam), stdin);
				newTeam[strlen(newTeam)-1] = '\0';
				fgets(newTeam, sizeof(newTeam), stdin);
				newTeam[strlen(newTeam)-1] = '\0';
				addTeam(newTeam, numOfTeams);
				numOfTeams++;
				printf("\nNew team added\n");
			}
		}		
		else if (menuChoice == 2)
		{
			printf("\t\tP\tW\tD\tL\tF\tA\tT\n\n\n");

				teams[i].lost, teams[i].goalsFor, teams[i].goalsAgainst,

I am trying to rewrite it into c++, but nothing good yet, i need to have same functions ect in c++.

[Grn Xtrm]

Just look up printing and getting input using cout<< and cin>>. Also, use

#include <iostream>
using namespace std;

That seems to be the only things you really need to change on first glance.
I'm sure William or someone else will correct me if I'm wrong.

You need to put return 0; at the end of main() and remove it from the end of the code. Remove the last 2 lines of the last code you posted.

[dinamit875]

when im removing return 0 from the end and putting it after main(),it gives me more errors:(:(

[Grn Xtrm]

Don't put it after main() put it within main() just before the right brace that terminates main().

i tryed to put in ";" after void function,but some errors are still there, if you have dev c++ compiler or anything similar please, try may be you will be able to fix them. thanks.

[jonsca]

typedef struct teams; should be typedef struct TeamInfo teams;
Change your cout on line 67 above to cout <

[dinamit875]

well i have made those changes, but having problems with:
void addTeam(char *teamName, int i)
and
void calculateResult(int t1, int t2, int t1R, int t2R)
the error is as follows:
90-129 lines expected primary-expression before '[' token
can anyone fix this problem???please.

[jonsca]

teams is not in scope for either of them. The functions have their own local scope and can't "see" the variables in main(). So, pass the array of structs into each of those, or I suppose you could use your function to return a new struct to be placed into the teams array.

Also, I noticed it before but cin >> newTeam, sizeof(newTeam), stdin; is probably not going to give you what you want, you don't need to specify those values, just take the input into newTeam with cin >>newTeam; .

I know what you mean, but i am not sure how would I imlement this in the code itself?could you please sypply me with the correct code, thanks.

[jonsca]

Couple of other little issues: You prompt for a new team twice
In your calculate results you 1.) declare a 1 element array(??) and 2.) you reference it's one element by index 1.
In main change your for loop

else if (menuChoice == 2)
		{
			cout << "\t\tP\tW\tD\tL\tF\tA\tT\n\n\n" << endl;
			for ( i = 0; i < 6; i++)

to i < numOfTeams

And change newTeam[strlen(newTeam)-1] = '\0'; to newTeam[strlen(newTeam)] = '\0'; otherwise you are truncating your string

As for the other part, add a parameter teams * teams I renamed it to teams * team and changed all your teams[i] to team[i] to avoid confusion.

[dinamit875]

yes,these changes are relevnt and i have made thembut still getting errors in void function, maybe problem is in the main()???

Your array teams does not exist in this function. In order to use it you must pass it in. Give your function (both functions, really) a parameter called teams for it to be available in your function body. The type of teams the array is[icode] teams* [/code] (not to match your array in your function, but to match your typedef up above). In main, you need to change your function calls to reflect the new parameter (which you can pass in as teams, to match your array name) e.g., addTeam(teams,newTeam, numOfTeams);

For your own sanity, you should probably change the name of the typedef or the name of the array.

You should change teams to something else for EITHER the typedef OR the variable. But leave it as it is for now, and change the declaration of addteam to void addTeam(T *,char[50],int) and the definition to void addTeam(T* T, char*teamName,int i) (first T is for the typedef,*,second T for your local variable in your function). Now, your variable T is within the scope of the function (when you have a free minute reread that section of your text on scope because it's crucial to know).
