Read a string and count the number of vowels,consonants and spaces in C

Algorithm

Input: Input a string
output: Displays the number of vowels, consonant and spaces

1. Start
2. scount = 0, vcount = 0, ccount = 0, i = 0
3. Read a string from the user say str
4. while ( str[i] != '\0')
   4.1 if str[i] = = 'a' || str[i] = = 'e' || str[i] = = 'i' || str[i] = = 'o' || str[i] = = 'u' 
     4.1.1 vcount++
   4.2 else if str[i]==' '
     4.2.1 scount++
   4.3 else
     4.3.1 ccount++
5. Print "The number of vowels in the string is",vcount
6. Print "The number of consonants in the string is",ccount
7. Print "The number of spaces in the string is",scount
8. Stop

C Program

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

int main()
{
int scount=0,vcount=0,ccount=0;
char str[30];
printf("Enter the string:");
gets(str);
for(int i=0;str[i]!='\0';i++) {
    if (str[i]=='a'||str[i]=='e'||str[i]=='i'||str[i]=='o'||str[i]=='u'){
        vcount++;
    }
   else if (str[i]==' '){
        scount++;
    }
    else {
        ccount++;
    }
}
printf("The number of vowels in the string is: %d\n",vcount);
printf("The number of consonants in the string is: %d\n",ccount);
printf("The number of spaces in the string is: %d\n",scount);

return 0;
}
