Question
MUST BE WRITTEN IN C++
Write a C++ program that reads in a sequence of characters and prints them in reversed order. You must use a stack. Implement these two function prototypes.
1. void push(char *stack, int top, char c);
2. char pop(char *stack, int top);
Use provided driver program to test your code. You should get the same output.
***********************DRIVER PROGRAM********************
int main()
{
string str;
cout<<"Please input a string: "<<endl;
cin>>str;
char *stack;
stack =new char[str.length()];
int top=0;
for(int i=0;i<str.length();i++)
{
push(stack,top,str[i]);
}
for(int j=0;j<str.length();j++)
{
cout<<pop(stack,top);
top--;
}
}
input and output:
Please input a string:
abcdefg
gfedcba
Program ended with exit code: 0
Explanation / Answer
#include <iostream>
using namespace std;
void push(char *stack, int top, char c);
char pop(char *stack, int top);
int main()
{
string str;
cout<<"Please input a string: "<<endl;
cin>>str;
char *stack;
stack =new char[str.length()];
int top=0;
for(int i=0;i<str.length();i++)
{
push(stack,top,str[i]);
top++;
}
for(int j=0;j<str.length();j++)
{
cout<<pop(stack,top);
top--;
}
}
void push(char *stack,int top,char c)
{
*(stack+top)=c;
}
char pop(char *stack,int top)
{
return *(stack+top-1);
}
