Question

C++ hashing code must read in an input file "input.txt", which is formatted as such:

add 0x20000000

addi 0x20000000

addiu 0x24000000

addu 0x21000000

and hash from an array with the values "0x2000000, 0x20000000, 0x24000000, 0x2100000" hard coded in.

Then the output must read the value and then the item such as add, addi, addiu, addu, making it look like:

0x200000000 add

0x200000000 addi

0x240000000 addiu

0x210000000 addu

Answer 1

Hi please find below code .Put this code in main.cpp and put your text file in same directory of code.compile and run the .Cpp file.

#include<iostream>
#include<fstream>
#include <string>
using namespace std;
int main() {
ifstream myReadFile;
string line,key,value;

//hardcoded values
string val[]={"0x2000000", "0x20000000", "0x24000000", "0x2100000"};

//Open the file to be read
myReadFile.open("input.txt");
int count=0;

//check if file is open
if (myReadFile.is_open()) {

//Read file line by line
while (getline(myReadFile,line)) {
stringstream s(line);

//Get the item in key from stringstream
s>>key;

//Print values from hardcoded array and item from #file
cout<<val[count]<<" "<<key<<endl;
count++;

}
}

//close file stream.
myReadFile.close();
return 0;
}
Output:

0x2000000 add 0x20000000 addi 0x24000000 addiu 0x2100000 addu
