Count Uppercase Lowercase Special characters


Write a C Program to Count Uppercase Lowercase Special characters in string. Here’s simple C Program to Count Uppercase Lowercase Special characters in string in C Programming Language.


C – Strings : 


Strings are actually one-dimensional array of characters terminated by a null character ‘\0’. Thus a null-terminated string contains the characters that comprise the string followed by a null.

String is a sequence of characters. char data type is used to represent one single character in C. So if you want to use a string in your program then you can use an array of characters.

The declaration and definition of the string using an array of chars is similar to declaration and definition of an array of any other data type.

Any string ends with a terminating null character ‘\0’. An array definition in such a way should include null character ‘\0’ as the last element.


Here is source code of the C Program to Count Uppercase Lowercase Special characters in string. The C program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/*  C Program to Count Uppercase Lowercase Special characters in string  */

#include<stdio.h>

int main()
{
    char text[100];
    int i;
    int countL,countU,countS;

    printf("Enter any string: ");
    gets(text);

    //here, we are printing string using printf
    //without using loop
    printf("\nEntered string is: %s\n",text);

    //count lower case, upper case and special characters
    //assign 0 to counter variables
    countL=countU=countS=0;

    for(i=0;text[i]!='\0';i++)
    {
        //check for alphabet
        if((text[i]>='A' && text[i]<='Z') || (text[i]>='a' && text[i]<='z'))
        {
            if((text[i]>='A' && text[i]<='Z'))
            {
                //it is upper case alphabet
                countU++;
            }
            else
            {
                //it is lower case character
                countL++;
            }
        }
        else
        {
            //character is not an alphabet
            countS++; //it is special character
        }
    }

    //print values
    printf("\nUpper case characters: [ %d ]\n",countU);
    printf("\nLower case characters: [ %d ]\n",countL);
    printf("\nSpecial characters: [ %d ]\n",countS);

    return 0;
}

OUTPUT : :


/*  C Program to Count Uppercase Lowercase Special characters in string  */

Enter any string: Hello Codezlub.

Entered string is: Hello Codezlub.

Upper case characters: [ 2 ]

Lower case characters: [ 11 ]

Special characters: [ 2 ]

Process returned 0
