checking if the characters in a string are either alphabets, numbers, or special characters. in c

i have been working on a question which asks to check the numbers,alphabets or other special characters in a string. for example if you are given two inputs. one is an integer which is string length and the second input is the string of characters. input1; 6 input2; 4!hs%5.

the output should be; noaaon. (n stands for number, a stands for alphabets, and o stands for other. i would appreciate if someone could help me .below is my code.

enter code here

`#include

include

int main(){

char c[20];

int n,i;

scanf("%d %s",&n,c);

for(i=1;c[i]<=n;i++)

if(i>='a' && i<='z')

printf("%c\n",(c[i]));

if(i=='!')printf("%c \n",i);

else{printf("%c \n",);}

return 0;} `
