When you're saving your image, it will ask you what quality of the image you want to use and it will show you that you're using a larger or smaller filesize depending on the quality of the image your saving.
<TIP> Make a duplicate layer before saving the image and uncheck the original. Always save the CS6 file too to re-edit later if need be. But that way you will have the file size you want and the original image is preserved
Answer:
C++ code for encryption is given below
Explanation:
#include <iostream>
using namespace std;
//functions to encrypt and decrypt
void encrypt(char str[]);
void decrypt(char str[]);
int main(){
char str[200];
bool done = false;
while(!done){
cout << "Enter a string (enter * to stop): ";
cin.getline(str, 200);
if(str[0] == '*' && str[1] == '\0')
done = true;
else{
encrypt(str);
cout << "Encrypted: " << str << endl;
decrypt(str);
cout << "Decrypted: " << str << endl;
}
cout << endl;
}
}
void encrypt(char str[]){
int i = 1;
for(int j = 0; str[j] != '\0'; j++){
str[j] += i;
i++;
if(i == 11)
i = 1;
}
}
void decrypt(char str[]){
int i = 1;
for(int j = 0; str[j] != '\0'; j++){
str[j] -= i;
i++;
if(i == 11)
i = 1;
}
}
