Question

C++ programming:

Write a function that counts the number of letters in the string using the following header:

int countLetters(char s[]){

}

Answer 1

#include<iostream>

#include<string.h>

int countLetters(char s[]);

using namespace std;

int main() {

char s[] = "a1b2c3d4efgh";

int count = countLetters(s);

cout<<"Count of alphabets in "<<s<<" is " <<count;

return 0;

}

int countLetters(char s[]){

int count = 0;

int size = strlen(s);

for(int a=0; a<size; a++){

if ((s[a]>=65 && s[a]<=90)||(s[a]>=97 && s[a]<=122)){

// If a character is capital or mall alphabet then count is incremented

count++;

}

}

return count;

}

Output:
