Thread: league table

hey everyone. theres a few things i need to find out if you consider helping me.

1. at the end of my program i want to print the points of the teams in descending order i.e if chelsea have 7 points and eveton have 9 points then i want everton to be top then chelsea underneath etc... so how do i specify that?
2. is there an easier way of writing that program does anyone know?

Code:

#include<stdio.h>
#include<stdlib.h>


int main()
{
    int points[4] = {0, 3, 1, 0};
    char a[20];
    char b[20];
    char c[20];
    char d[20];
    int x = 1;
    int i;
    int aa;
    int bb;
    int cc;
    int dd;
    int ptsa=0;
    int ptsb=0;
    int ptsc=0;
    int ptsd=0;


    printf("enter the teams:\n");
    fgets(a, 20, stdin);
    fgets(b, 20, stdin);
    fgets(c, 20, stdin);
    fgets(d, 20, stdin);
printf("%s will play %s\n",a,b);
printf("enter %s score\n",a);
scanf("%d",&aa);
printf("enter %s score\n",b);
scanf("%d",&bb);


        if(aa>bb)
            {
                ptsa = ptsa + points[1];
            }


                    else if(aa<bb)
                        {
                            ptsb = ptsb + points[1];
                        }
                            else if(aa==bb)
                            {
                                ptsa = ptsa + points[2];
                                ptsb = ptsb + points[2];

}

ye but how could i go about using functions?

so for relational i could go if(a>b && a>c && a>c && a>d ) printf.......?

Specifically, I can't say because your code lacks comments or meaningful identifiers. However, one of the general ideas behind the use of functions is to reduce code duplication. Eg, it looks (at a glance) like the sections from line 52-71, 74-93, 94-114, 117-136, and 139-158 do something very similar just with different variables. So you should write one function with appropriate parameters, and call it 5 times with the different variables.

If they don't do exactly the same thing, you can definitely extract some smaller sections that are the same and make those functions. You can use both the return value and pointers in the parameter list to set values back in main, eg:

Code:

int somefunc (int a, int b, int *x);  // prototype
int data1, data2, result1, result2;
// assign to data1 and data2
result1 = somefunc(data1, data2, &result2);

Here the "data" variable pass values into the function, and the "result" variables receive values from it. Since a function can only have one return type, param x is a pointer you can deference and assign to inside somefunc:

Code:

*x = 666;

thank you very much for your input mate
