Question

Write a complete program using two arrays, upper and lower to keep the upper

And lower alphabet respectively.

Ask the user to enter string example:

This is a test. Soon you will see the future.

Your program should parse the string and keep track of number of alphabet. Both arrays are indexed from 0 to 25. The logical way to do this is to use upper[0] to

Count the number of 'A' and upper[1] to count number of 'B' and so on. Likewise

For the lower array.

Output should look like:

A: 0            a:2

B: 0            b:0

Explanation / Answer

#include<stdio.h>

#include<conio.h>

#include<ctype.h>

void main()

{

int i,len;

char s[100];

int upper[26]={0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

int lower[26]={0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

clrscr();

printf("enter a string ");

gets(s);

len=strlen(s);

for(i=0;i<len;i++)

{

if(isupper(s[i]))

{

upper[s[i]-65]++;}

if(islower(s[i]))

{

lower[s[i]-97]++;}

}

for(i=0;i<26;i++)

{

printf("%c:%d %c:%d ",'A'+i,upper[i],'a'+i,lower[i]);

}

getch();

}
