Question

#include <stdio.h>
#include <string.h>
#define max 100000
int main()
{
char arr[max];
int c_num=0,ch_num=0,i;

fgets(arr,sizeof(arr),stdin);
int size=strlen(arr);

for(i=0;i<size;i++)
{
if(arr[i]<=9 || arr[i]>=0)
c_num++;
if(arr[i]=='!' || arr[i]=='@' ||arr[i]=='#' ||arr[i]=='

Answer 1

Number characters are in the range 48 to 57 inclusive. Not 0 to 9.

Also your if(arr[i]<=9 || arr[i]>=0) is not the correct expression to check if a character is between '0' and '9' even if you fix the previous mistake.

Answer 2

Thank u soo much😇😇
