How to count alphabets, numeric and special characters ?
In this example, we have to count digits, spaces, special characters and alphabets using C program.
#include <stdio.h>
int main()
{
char str[100];
int countDigits,countAlphabet,countSpecialChar,countSpaces;
int counter;
//assign all counters to zero
countDigits=countAlphabet=countSpecialChar=countSpaces=0;
printf("Enter a string: ");
gets(str);
for(counter=0;str[counter]!=NULL;counter++)
{
if(str[counter]>='0' && str[counter]<='9')
countDigits++;
else if((str[counter]>='A' && str[counter]<='Z')||(str[counter]>='a' && str[counter]<='z'))
countAlphabet++;
else if(str[counter]==' ')
countSpaces++;
else
countSpecialChar++;
}
printf("\nDigits: %d \nAlphabets: %d \nSpaces: %d \nSpecial Characters: %d",countDigits,countAlphabet,countSpaces,countSpecialChar);
return 0;
}Output :
Enter a string: wikitechy, 789@#%12.
Digits: 5
Alphabets: 9
Spaces: 1
Special Characters: 5
