Write a program in c++ which read two matrix and then print a matrix which is addition of these two matrix.

Coding:- 

                    #include<iostream.h>

void main()

{
 int a[2][3],b[2][3],c[2][3];

 for(i=0;i<=1;i++)
 {

for(j=0;j<=2;j++)
cin>>a[i][j];


 }
cout<<"the matrix is : \n";

 for(i=0;i<=1;i++)
 {

for(j=0;j<=2;j++)
 cout<<"  "<<a[i][j];

 cout<<"\n";


 }
   
 cout<<"enter values in 2nd matrix  \n";
 for(i=0;i<=1;i++)
 {

cin>>b[i][j];


 }
cout<<"the matrix is : \n";

 for(i=0;i<=1;i++)
 {

 cout<<"  "<<b[i][j];

 cout<<"\n";


 }
           for(i=0;i<=1;i++)
 {

for(j=0;j<=2;j++)

 c[i][j]=a[i][j]+b[i][j];

cout<<"\n";

}

         cout<<"the sum of two matrix is: = \n" ;

         for(i=0;i<=1;i++)
 {

for(j=0;j<=2;j++)
 cout<<"  "<<c[i][j];

 cout<<"\n";
} }

Write a Program in c++ which read 6 no. from keyboard and store these no into array and then calculate sum of these no. using function.

Coding:- 

 #include<iostream.h>
 int sum (int a[])
 {
int n=0;
for(int i=0;i<=5;i++)
n=n+a[i];
return (n);
 }

 int output(int a[])

 {
cout<<"the elements of array are : "<< endl ;

for(int i=0;i<=5;i++)

cout<<a[i]<<endl;

 }

 int main()

 {
 int a[6],s,i;
 cout<<"enter 6 elements : ";
 for(i=0;i<=5;i++)
 cin>>a[i];

 output(a);

 cout<<"sum of array element is : ="<<sum(a)<<endl;


 }

Output:- 
   

Write a Program in c++to input the marks of five students in an array and then print all the marks.

Coding:- 

  #include<iostream.h>
void main()
{
 int marks[5] ;
int i;


 cout<<"enter marks of five students ";

 for(i=0;i<=4;i++)
 {
cin>>marks[i];
 }


cout<<"the marks of students are: \n";

 for(i=0;i<=4;i++)

 cout<<"marks of " << i+1<<"student is :" << marks[i]<<endl;
