Count the number of letters, digits and special characters in C program-CodePudding

So here is my code and I am struggling with the ispunct(); it starts counting in 8 and in isalpha() it starts counting in 1 so I print it noAlpha-1, but in ispunct() it is awkward to put noSpecial-8 to become accurate. I don't have any issues in digits. What might be the problem here?

#include<stdio.h>
#include<ctype.h>

int main(){
    
    char string[100];
    int i, noAlpha, noDigit, noSpecial;
        
       printf("Input the string : ");
       gets(string);    

 
        noAlpha=0;
        noDigit=0;
        noSpecial=0;
        
        for(i=0;i<100;i  ) {
     
        if(isalpha(string[i]))
        noAlpha  ;
    
        
        if(isdigit(string[i]))
        noDigit  ;
        
        if(ispunct(string[i]))
        noSpecial  ;
    }
        
        printf("Number of Alphabets in the string is %d\n", noAlpha-1);
        printf("Number of Digits in the string is %d\n", noDigit);
        printf("Number of Special characters in the string is %d\n", noSpecial);
}

The function gets is unsafe and is not supported by the C Standard.

Either use fgets like

fgets( string, sizeof( string ), stdin );

or scanf like

scanf( "
