I'm crazy doing it at mindnigt

#include<stdio.h>
#include<conio.h>
#include<string.h>
int main()
{
    char str[25],a;
    int count=0,i;

    printf("Enter a word:");
    scanf("%d",&str);

    a=strlen(str);

    for(i=0; i<a; i++){
        if(strcmp(str,'a')==0)
            count++;
        else if(strcmp(str,'e')==0)
            count++;
        else if(strcmp(str,'i')==0)
            count++;
        else if(strcmp(str,'o')==0)
            count++
        else if(strcmp(str,'u')==0)
            count++;
        else
            count = count + 0;
    }
    printf("The number of vowels is %d",count);
    printf("The number of consonznts is %d",strlen-count);
    getch();
    return 0;
