C Programming: Count total number of alphabets, digits and special characters
C String: Exercise-7 with Solution
Write a program in C to count total number of alphabets, digits and special characters in a string.
Sample Solution:
C Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define str_size 100 //Declare the maximum size of the string
void main()
{
char str[str_size];
int alp, digit, splch, i;
alp = digit = splch = i = 0;
printf("\n\nCount total number of alphabets, digits and special characters :\n");
printf("--------------------------------------------------------------------\n");
printf("Input the string : ");
fgets(str, sizeof str, stdin);
/* Checks each character of string*/
while(str[i]!='\0')
{
if((str[i]>='a' && str[i]<='z') || (str[i]>='A' && str[i]<='Z'))
{
alp++;
}
else if(str[i]>='0' && str[i]<='9')
{
digit++;
}
else
{
splch++;
}
i++;
}
printf("Number of Alphabets in the string is : %d\n", alp);
printf("Number of Digits in the string is : %d\n", digit);
printf("Number of Special characters in the string is : %d\n\n", splch);
}
Sample Output:
Count total number of alphabets, digits and special characters : -------------------------------------------------------------------- Input the string : Welcome to w3resource.com Number of Alphabets in the string is : 21 Number of Digits in the string is : 1 Number of Special characters in the string is : 4

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
