C Program To Count The Number Of Vowels, Consonants, Digits And Special Characters Using File Management Concepts.

In this program input is given by one file and File variable read character one by one from this file.

Input File

Programmer Jd @123

Save this input text file with any name. like input.txt

Code

#include<stdio.h>

#include<string.h>

#include<stdlib.h>

int main(){

char str[100];

int i=0;

int vowels=0,consonant=0,digit=0,symbols=0,spaces=0;

FILE *fp;

char ch;

fp = fopen("input.txt", "r");

    if (fp == NULL)

    {

        printf("File not opened ");

        exit(1);

    }

    ch = fgetc(fp);

    printf("Your string is :\n");

    while (!feof(fp))

    {

        str[i++]=ch;

        ch = fgetc(fp);

    }

    str[i]='\0';

    printf("%s",str);

    fclose(fp);

for(i=0;str[i]!='\0';i++)

}

else if((str[i]>='a' && str[i]<='z')||(str[i]>='A' && str[i]<='Z'))

{

consonant++;

}

else if(str[i]>='0' && str[i]<='9'){

digit++;

}

else if (str[i]==' ')

{

spaces++;

}

else{

symbols++;

}

}

printf("\nVowels : %d",vowels);

printf("\nConsonant : %d",consonant);

printf("\nDigit : %d",digit);

printf("\nSpecialSymbols : %d",symbols);

printf("\nWhite spaces: %d", spaces);

return 0;

}
