Answer 1

Hi

Please find the snapshot for the code, test file and output, for the required program, I have added the comments in thee code for the ease of your understanding.

******** SNAPSHOT ******

#include<iostream> #include<fstream> #include<string> using namespace std; int main(void) FILE *fp; int c; int count =0; //To store the aplhabet count fp = fopen("test.txt", "r"); //fgetc is used to read the charater from file stream fp //And the condtion runs till the EOF while((c = fgetc(fp)) != EOF) { //This condition is used to check if the character is an alphabet if((c > 63 && c < 91) or (c > 96 && c < 123)), count++; cout << "Total alphabet in count is "<<count; fclose(fp); return 0;

************ OUTPUT **********

Total alphabet in count is 9

******** CODE ********

#include<iostream>

#include<fstream>

using namespace std;

int main(void)

{

    FILE *fp;

    int c;

    int count =0; //To store the aplhabet count

    fp = fopen("test.txt", "r");

    //fgetc is used to read the charater from file stream fp

    //And the condtion runs till the EOF

    while((c = fgetc(fp)) != EOF) {

        //This condition is used to check if the character is an alphabet

        if((c > 63 && c < 91) or (c > 96 && c < 123))

                        count++;

    }

    cout << "Total alphabet in count is "<<count;

    fclose(fp);

    return 0;

}
