addition(a,size1,b,size2,add,size2+size1+1);
display(add,size1+size2+1);

}

addition isnt working correctly. the individual a and b are storing it perfectly by the addition isnt working. please also explain the reason why its not giving accurate value as well as fix it

Answer:

Code after fixing the errors in the given code:

There are some indentation errors in the code, because of those errors in some lines of code result in wrong output, I fixed those errors , please check the below code and run in any online C++ compiler for better experience

#include <iostream>

using namespace std;
struct node
{
int base;
int power;
};

void insert(node ptr[],int basee,int powerr)
{
ptr[powerr].power=powerr;
ptr[powerr].base=basee;

}
void addition(node ptr1[],int size1,node ptr2[],int size2,node ptr3[],int size3)
{
for(int j=0;j<=size1;j++)
{
ptr3[j].base=(ptr3[j].base)+(ptr1[j].base);
}
for(int j=0;j<=size2;j++)
{
ptr3[j].base=(ptr3[j].base)+(ptr2[j].base);
}

}

void display(node ptr[],int size)
{
if(ptr[0].base!=0){
cout<<ptr[0].base<<"+";}
for(int i=1; i<=size; i++)
{
if(ptr[i].base!=0){
cout<<ptr[i].base<<"x^"<<ptr[i].power<<"+";}
}
}

int main()
{
bool choice1=true;
bool choice2=true;
int size1,size2,base1,base2,power1,power2;
cout<<"enter the max power in polynominal 1: ";
cin>>size1;
node *a= new node[size1+1];
for(int i=0; i<(size1+1); i++)
a[i].base=0;
while(choice1==true)
{
cout<<" enter the base,the power of x: ";
cin>>base1>>power1;
insert(a,base1,power1);
cout<<endl<<"1:write another value in this equation, 0:end"<<endl;
cin>>choice1;
}
display(a,size1);

cout<<"enter the max power in polynominal 2: ";
cin>>size2;
node *b= new node[(size2+1)];
for(int i=0; i<(size2+1); i++)
b[i].base=0;
while(choice2==true)
{
cout<<" enter the base,the power of x: ";
cin>>base2>>power2;
insert(b,base2,power2);
cout<<endl<<"1:write another value in this equation, 0:end"<<endl;
cin>>choice2;
}
display(b,size2);

node *add=new node[(size1+size2+1)];
for( int i=0; i<(size2+1+size1); i++)
add[i].base=0;

addition(a,size1,b,size2,add,(size2+size1+1));
display(add,(size1+size2+1));

}

Output:
