Question

how can i make this c++ code so i can write " the quick brown fox" in the input instead

#include <iostream>
#include<bits/stdc++.h>
using namespace std;

bool checkPangram (string &phrase)
{

vector<bool> check(26, false);

int index;

for (int i=0; i<phrase.length(); i++) {

if (phrase[i] >= 'A' && phrase[i] <= 'Z') {
index = phrase[i] - 'A';
} else if(phrase[i] >= 'a' && phrase[i] <= 'z') {
index = phrase[i] - 'a';
}

check[index] = true;
}

for (int i=0; i< 26; i++) {
if (!check[i]) {
return (false);  
}  
}
return (true);
}

int main()
{
string phrase = "the quick brown fox jumps over the crazy dog !!";
if (checkPangram(phrase)) {
cout << "This is a pangram";
} else {
cout << "This is not a pangram";
}
return 0;
}

Explanation / Answer

Following are two types

#include <iostream>
#include<bits/stdc++.h>
using namespace std;

bool checkPangram (string &phrase)
{

vector<bool> check(26, false);

int index;

for (int i=0; i<phrase.length(); i++) {

if (phrase[i] >= 'A' && phrase[i] <= 'Z') {
index = phrase[i] - 'A';
} else if(phrase[i] >= 'a' && phrase[i] <= 'z') {
index = phrase[i] - 'a';
}

check[index] = true;
}

for (int i=0; i< 26; i++) {
if (!check[i]) {
return (false);  
}  
}
return (true);
}

int main()
{
string phrase = "the quick brown fox"; // this is the input string
if (checkPangram(phrase)) {
cout << "This is a pangram";
} else {
cout << "This is not a pangram";
}
return 0;
}

// Output: This is not a pangram

#include <iostream>
#include<bits/stdc++.h>
using namespace std;

bool checkPangram (string &phrase)
{

vector<bool> check(26, false);

int index;

for (int i=0; i<phrase.length(); i++) {

if (phrase[i] >= 'A' && phrase[i] <= 'Z') {
index = phrase[i] - 'A';
} else if(phrase[i] >= 'a' && phrase[i] <= 'z') {
index = phrase[i] - 'a';
}

check[index] = true;
}

for (int i=0; i< 26; i++) {
if (!check[i]) {
return (false);  
}  
}
return (true);
}

int main()
{
string phrase;
cout << "Enter a phrase:"; // prompting for user input
getline(cin,phrase); // this line is to take input
if (checkPangram(phrase)) {
cout << "This is a pangram";
} else {
cout << "This is not a pangram";
}
return 0;
}

/* SAMPLE OUTPUT
Enter a phrase: the quick brown fox
This is not a pangram
*/
