Suppose X, Y, Z are arrays of integers of size M, N and M+N respective

1.	Suppose X, Y, Z are arrays of integers of size M, N and M+N respectively. The numbers in array X and Y appear in descending order.Write a user defined function in C++ to produce third array Z by merging arrays X and Y in descending order.
Answer» #include <iostream.h> void Merge(int X[],int M,int Y[],int N,int Z[]); int main() { int X[50],Y[50],Z[50],MN=0,M,N; cout<<"How many elements do U want to create first array with? "; cin>>M; cout<<"Enter First Array's elements [descending]..."; for(int i=0;i>X[i]; cout<<"How many elements do U want to create second array with? "; cin>>N; MN=M+N; cout<<"Enter Second Array's elements [descending]..."; for(int i=0;i>Y[i]; Merge(X,M,Y,N,Z); cout<<"The merged array is...."; for(i=0;i<MN;i++) cout<<Y[i]<<" "; cout<<end1; return 0; } void Merge(int X[],int M,int Y[],int N,int Z[]) { int x,y,z; for(x=-1,y=-1,z=-1;x>=0&&y>=0;) { if(X[x]<=Y[y]) Z[z--]=X[x--]; else Z[z--]=Y[y--]; } if(x<0) { while(x>=0) Z[z--]=X[x--]; } else { while(y>=0) Z[z--]=Y[y--]; } }

#include <iostream.h>

void Merge(int X[],int M,int Y[],int N,int Z[]);

int main()

{ int X[50],Y[50],Z[50],MN=0,M,N;

cout<<"How many elements do U want to create first array with? ";

cin>>M;

cout<<"Enter First Array's elements [descending]..."; for(int i=0;i>X[i];

cout<<"How many elements do U want to create second array with? ";

cin>>N; MN=M+N;

cout<<"Enter Second Array's elements [descending]...";

for(int i=0;i>Y[i];

Merge(X,M,Y,N,Z);

cout<<"The merged array is....";

for(i=0;i<MN;i++)

cout<<Y[i]<<" ";

cout<<end1;

return 0;

}

void Merge(int X[],int M,int Y[],int N,int Z[])

{ int x,y,z;

for(x=-1,y=-1,z=-1;x>=0&&y>=0;)

{ if(X[x]<=Y[y]) Z[z--]=X[x--];

else Z[z--]=Y[y--];

}

if(x<0)

{ while(x>=0)

Z[z--]=X[x--];

}

else

{

while(y>=0)

Z[z--]=Y[y--];

}
