How can I input more than one mark ?

Question

Now I have five marks , and I want to input them and get their sum .
first : int marks[5];
second :
cin>>first mark;
cin>>second mark;
cin>>third mark;
cin>>fourth mark;
cin>>fifth mark;

third : sum= first mark + second mar......

how can I write them in c++?

Answer 1

@enas, That's why I'm here 😉

Answer 2

Yes you can and you should.

Answer 3

if it is the real code,
you must include the appropriate header files, put all above stuff in main() function and inside main() function body,
you MUST declare the array as-

int marks[5];

Answer 4

Use loops,
eg. of for loop,

int sum=0;
for(int i=0;i<5;i++)
{
cin>>marks[i];
sum=sum+marks[i];
}

cout<<"Sum= "<<sum;

Answer 5

@enas,
In your code, you declare variable i twice,
once above for loop and once inside for loop, it causes error.
just declare variable i at line 1
and initialise it with 0 (as i=0, not int i=0) inside for loop.

Answer 6

@Sachin's way is correct.

Just FYI, array index 0 corresponds to first element, and 1 corresponds to second element, and so on.

E.g.

cin >> marks[0];
cin >> marks[1];

sum = marks[0] + marks[1];

Answer 7

your code is good .but it is missing (cout<<) and (n)isn't declared in the scope .. nice try 👍

Answer 8

great . but I made some modification.

Answer 9

int sum=0,i=0,marks[5];
for(int i=0;i<5;i++)
{
cin>>marks[i];
sum=sum+marks[i];
}

cout<<"Sum= "<<sum;

Answer 10

thank you @Sachin Artani very much.

Answer 11

AAh ,another perfect one ,thank you Hatsy Rei.

Answer 12

@Sachin Artani . you are right

Answer 13

but I should write int marks[5] . right ?

Answer 14

I hope I didn't annoy you !..thank you :)

Answer 15

you Illuminate my post 😀.good luck .

Answer 16

I had a mistake

Answer 17

@Sachin Artani .actually, I ran the code without writing i in the first line ( with int ),but it didn't work... did you run my code.?

Answer 18

#include <iostream>
using namespace std;
main (){
int mark[5];
for (int i = 0; i<5; i++)
cin >> mark[n];
return 0;
}
