Question

c++

Write a program that reads 10 marks of type float, store them in an array, then the program will 4 determine the number of marks greater than the average. Write a program that reads 10 marks, store them in an array, then the program will print the .5 array in reverse order.

Answer 1

Ans 4.)

#include<iostream>
using namespace std;

int main(){
float arr[10],sum=0,avg;
cout<<"Enter 10 marks: \n";
for(int i = 0; i < 10; i++){
        cin >> arr[i]; // input number
        sum += arr[i]; // sum number
}
avg = sum/10.0; // find avg
int count = 0;
for(int i = 0; i < 10; i++){
        if(arr[i] > avg){
            count++;   // count number of marks greater
       }
}
cout<<"Average: "<<avg<<endl; // you can remove it
cout<<"Number of marks greater than average: "<<count;
return 0;
}

#include<iostream> using namespace std; int main({ float arr[10], sum=0, avg; cout<<"Enter 10 marks: \n"; for(int i = 0; i <10; i++){ cin >> arr[i]; // input number sum += arr[i]; // sum number avg = sum/10.0; // find avg int count = 0; for(int i = 0; i <10; i++){ if(arr[i] > avg) { I count++; // count number of marks greater cout<<"Average: "<<avg<<endl; // you can remove it cout<<"Number of marks greater than average: "<<count; return 0;

/*OUTPUT */

Enter 10 marks: 2.5 6.4 3.9 4.5 1.2 3.8 5.6 4.8 9.8 10.5 Average: 5.3 Number of marks greater than average: 4 -- --------- Process exited after 30.65 seconds with return value o Press any key to continue . ..

Ans 5)

#include<iostream>
using namespace std;

int main(){
float arr[10],avg; // CREATE VARIABLE
cout<<"Enter 10 marks: \n"; // ASK USER
for(int i = 0; i < 10; i++){ //
        cin >> arr[i]; // input number
}
cout<<"Array in raverse order:\n";
for(int i = 9; i >= 0; i--){ // print reverse array store from 0 to n-1
        cout<<arr[i]<<endl;
}
return 0;
}

/* OUTPUT */

Enter 10 marks: 3.2 5.6 9.4 5.9 2.3 6.4 15.7 3.89 14.8 4.7 Array in raverse order: 4.7 14.8 3.89 15.7 6.4 2.3 5.9 9.4 5.6 3.2 Process exited after 27.32 seconds with return value o Press any key to continue ...
