Quality control is a system of maintaining standards in manufactured products by testing a sample of the output against the specification.
A vital part of any website project is the quality assurance stage. Prior to launch, final QA testing ensures that your site is working according to your expectations and that your site users won’t be frustrated with any non-functioning pages.
In psuedocode it would be:
length = input()
width = input()
area = length * width
print(area + " sq ft");
Answer:
hope this helps!
Explanation:
#include <iostream>
#include <fstream>
using namespace std;
void print_histogram(int counter[26])
{
for(int i = 0; i < 26; ++i){
cout << (char)(i+97) << " ";
for(int j = 0; j < counter[i]; ++j){
cout << (char)254;
}
cout << endl;
}
}
int main()
{
int counter[26] = {0};
string filename = "data.txt";
char byte = 0;
// opens file in read mode
ifstream input_file(filename);
if (!input_file.is_open()) {
cerr << "Could not open the file - '"
<< filename << "'" << endl;
return EXIT_FAILURE; // exit if not opened
}
// reads every character from the file
while(input_file.get(byte)){
if(byte >= 97 && byte <= 122){
++counter[byte-97];
}
}
print_histogram(counter); // required print histogram function
return 0;
}
