Question
C++
(Count vowels and consonants, file input, nested-loops, switch statement) Assume that letters A, E, I, O and U are the vowels. Write a program that reads strings from a text file, one line at a time, using a while-loop. You do the following operations within each loop: Read one line from the input file and store it in a string; Count the number of vowels and consonants (using either while-loop or for-loop) in the file string. The while-loop will terminate when the end-of-file is reached. After the loop is finished, the program displays the total number of vowels and consonants in the text file.
[A text file, named “ass4_Q6_input.txt”, is provided as your testing input file.]
This what is going to be in the input file.
Explanation / Answer
#include<process.h>
#include <stdio.h>
void main(int argc,char *argv[])
{
FILE *filepointer1;
int vowels=0,consonants=0;
char characters;
clrscr();
if(argc!=2)
{
printf("There are insufficient Arguments");
exit(0);
}
filepointer1=fopen(argv[1],"r");
if(filepointer1==NULL)
{
printf("This source is unable to be opened");
exit(0);
}
ch=fgetc(filepointer1);
while(ch!=EOF)
{
if((ch=='a')||(ch=='A')||(ch=='e')||(ch=='E')||(ch=='i')||(ch=='I')||(ch=='o')
||(ch=='O')||(ch=='u')||(ch=='U'))
{
vowels++; // number of vowels incremented
}
else
{
consonanst++; // number of consonant increented
}
ch=fgetc(filepointer1);
}
printf(" The number of vowels are = %d",vowels);
printf(" The number of consonant are = %d",consonants);
getch();
}
