Need help sorting many values from highest to lowest

I am trying to make a program that sorts 26 different values in order.
e.x:
D: 7
E: 5
A: 4
C: 2
B: 1

Here is my program code for getting the values(This code works):

Code:

int main
{
    char num=0;
    int end=0;
    int a=0;
    int b=0;
    int c=0;
    int d=0;
    int e=0;
    int f=0;
    int g=0;
    int h=0;
    int i=0;
    int j=0;
    int k=0;
    int l=0;
    int m=0;
    int n=0;
    int o=0;
    int p=0;
    int q=0;
    int r=0;
    int s=0;
    int t=0;
    int u=0;
    int v=0;
    int w=0;
    int x=0;
    int y=0;
    int z=0;

    printf("Press a keyboard button: ");
    for (end == end; end == 0;){
        num = getch();
        switch (num)
        {
        case '0': end=1; break;
        case 'a': a++; break;
        case 'b': b++; break;
        case 'c': c++; break;
        case 'd': d++; break;
        case 'e': e++; break;
        case 'f': f++; break;
        case 'g': g++; break;
        case 'h': h++; break;
        case 'i': i++; break;
        case 'j': j++; break;
        case 'k': k++; break;
        case 'l': l++; break;
        case 'm': m++; break;
        case 'n': n++; break;
        case 'o': o++; break;
        case 'p': p++; break;
        case 'q': q++; break;
        case 'r': r++; break;
        case 's': s++; break;
        case 't': t++; break;
        case 'u': u++; break;
        case 'v': v++; break;
        case 'w': w++; break;
        case 'x': x++; break;
        case 'y': y++; break;
        case 'z': z++; break;
        }
    }

    printf("\nA: %d\nB: %d\nC: %d\nD: %d\nE: %d\nF: %d\nG: %d\nH: %d\nI: %d\nJ: %d\nK: %d\nL: %d\nM: %d\nN: %d\nO: %d\nP: %d\nQ: %d\nR: %d\nS: %d\nT: %d\nU: %d\nV: %d\nW: %d\nX: %d\nY: %d\nZ: %d\n", a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z);
    getchar();
    return 0;
}

I get my values, but I can't sort them in order. Please help!

Thanks.

Don't use 26 different variables. Use an array or better yet, a vector. There should be info about arrays & vectors in the FAQ section if you haven't used them yet.

Oh my gosh; A thousand times "No!"

Lack of thinking "There must be a better way" will get you nowhere as a programmer.
Go forth and seek out how other people solve this kind of thing.
