Question
Convert the following code from C++ to C to get the same output below. provide screenshot
#include <stdio.h>
#include<iostream.h>
#include <conio.h>
#include<string.h>
#include<math.h>
#include<stdlib.h>
main()
{
long int p,g,Sa=0,Sb=0,Ta,Tb,Skey1,Skey2,Skey;
clrscr();
cout<<"Enter a Value for p :";
cin>>p;
cout<<" Enter a Value for g :";
cin>>g;
//======== Generate Sa and Sb Values Randomly between 0 and 20
Sa=random(20);
Sb=random(20);
//======== Calculate Ta and Tb Values
Ta=(pow(g,Sa));
Ta=Ta%p;
Tb=(pow(g,Sb));
Tb=Tb%p;
//======== Calculate Secret Key Values
Skey1=(pow(Tb,Sa));
Skey1=Skey1%p;
Skey2=(pow(Ta,Sb));
Skey2=Skey2%p;
if(Skey1==Skey2)
Skey=Skey1;
//========= Print Secret Key Value
cout<<" The random Number of SA is :"<<Sa;
cout<<" The random Number of SA is :"<<Sb;
cout<<" The Value of Secret Key is :"<<Skey;
getch();
return 0;
}
Enter a Value for p Enter a value for g 17 The random Number of SA is :3 The random Number of SA is :6 The Value of Secret Key is :1-Explanation / Answer
#include <stdio.h>
#include <conio.h>
#include<string.h>
#include<math.h>
#include<stdlib.h>
#include<time.h>
main()
{
long p,g,Sa=0,Sb=0,Ta,Tb,Skey1,Skey2,Skey;
clrscr();
srand (time(NULL));
printf("Enter a Value for p :");
scanf("%ld", &p);
printf("Enter a Value for g :");
scanf("%ld", &g);
//======== Generate Sa and Sb Values Randomly between 0 and 20
Sa=rand() % 20;
Sb=rand() % 20 ;
//======== Calculate Ta and Tb Values
Ta=(pow(g,Sa));
Ta=Ta%p;
Tb=(pow(g,Sb));
Tb=Tb%p;
//======== Calculate Secret Key Values
Skey1=(pow(Tb,Sa));
Skey1=Skey1%p;
Skey2=(pow(Ta,Sb));
Skey2=Skey2%p;
if(Skey1==Skey2)
Skey=Skey1;
//========= Print Secret Key Value
printf(" The random Number of SA is : %ld", Sa);
printf(" The random Number of SA is : %ld", Sb);
printf(" The Value of Secret Key is : %ld ", Skey);
getch();
return 0;
}
Output:
g++ -std=c++11 -o main *.cpp
sh-4.2$ main
Enter a Value for p :7
Enter a Value for g :17
The random Number of SA is : 4
The random Number of SA is : 9
The Value of Secret Key is : 1
