    Character count program

    I have the character count program that works like it should, but I can't figure out code to count the number of non-alphanumeric characters. Non alphanumeric characters are !@#$%^&*() basically they are any characters that do not contain the value of a number or a letter. Is there code to find non-alphanumeric characters?

    Code:
    #include<stdio.h>
    #include<conio.h>
    
    void main()
    {
    int length=0,upper=0,lower=0,digits=0;
    char str[80];
    char strlen[80];
    int i;
    
    printf("\nEnter The String : ");
    gets(str);
    
    
    i=0;
    
    while(strlen[length]!='\0')
            length++;
    
    while(str[i]!='\0')
      {
      if(str[i]>='A' && str[i]<='Z')
         upper++;
      if(str[i]>='a' && str[i]<='z')
         lower++;
      if(str[i]>='0' && str[i]<='9')
    	 digits++;
    
      i++;
      }
    
     printf("\nLength of the String is : %d",length);
     printf("\nUppercase Letters : %d",upper);
     printf("\nLowercase Letters : %d",lower);
     printf("\nDigits : %d",digits);
    
    
    
        getch();
     }

    Do you want to "roll your own", or use the standard functions?

    I believe you have the answer <from the other forum>. no 's' in ctype.h
