#include   // for isalpha

void InputAndCheck(int * pValue, const char * pName)
{
    do

        printf("Enter a value for %s: ", pName);
        scanf("%d", pValue);
        if (isalpha(*pValue))
        {
            printf("INPUT ERROR!\n");
            continue;
        }
        else

    fflush(stdin);
    return;
}

int main()
{
    int a, b, c;
    InputAndCheck(&a, "a");
    InputAndCheck(&b, "b");
    InputAndCheck(&c, "c");
    printf("a=%d;b=%d;c=%d;\r\n",a,b,c);
    return 0;
}
