C++

Question

A robot can type 300 letters per minute.
The given program takes the text input time (in minutes).

Task
Complete the code to calculate and output the number of letters that will be typed in a given time.

Sample Input
20

Sample Output
6000

Hint
To calculate the length of the text, you need to multiply the time by a count (letters per minute). Attempt in comments

Answer 1

Tanvir, you forgot to declare the variable "result"

Corrected code:
#include <iostream>
using namespace std;

int main() {
int speed = 300; //speed of the robot
int time, result; //declare variables
cin >> time; //input the time
result = time * speed;
cout << result; //output the result

return 0;
}

Answer 2

include <iostream>
using namespace std;

int main() {

int computer = 300;
int time;
cin >> time ;
result = computer * time;
cout << result ;

return 0;
}

Does this work??

Answer 3

#include <iostream>

int result = computer * time;

Answer 4

Doesnt work though

Answer 5

Nope

Answer 6

Yeah... That's it.. Thanks Simba

Answer 7

#include<iostream>
using namespace std;

int main ()
{
int n; // n is given time
cin>>n;
cout<<n*300;
return 0;
}

Answer 8

#include<iostream>
int main()
{
int n = 300;
int time;
cin>>time;
cout<<n*time;
return 0;
}

Answer 9

include <iostream>
using namespace std;

int main() {

int computer = 300;
int time = 1;
cin >> time * computer;
cout << time ;

return 0;
}

Answer 10

Yay... You made the solution urself...

Answer 11

Oh... I didn't test that btw...
😅😅😅

Answer 12

What's the error..?? I mean, can u please tell me.. I am not in a position to test it... Sorry

Please correct me... I am new to cpp

Answer 14

Thanks Chris

Answer 15

#include < iostream>
Using namespace std;
Int main()
{
Double time,letters;
/*Double will be used because time can be in hours and minutes both */
Cin>>time ;
Letters = 300* time ;
Cout <<letters;
Return 0 ;
}

Answer 16

int count = 300; // letter in a minute
int time = 20;

cin >> time;

//your code goes here
count *= time;

cout << count << endl;

Answer 17

#include <iostream>
using namespace std;

int main() {
int speed = 300; //speed of the robot
int time, result; //declare variables
cin >> time; //input the time
result = time * speed;
cout << result; //output the result

return 0;
}

Good Luck
