/*The Caesar cipher is a type of substitution cipher in which each letter in the plaintext is shifted to a certain number of places down the alphabet. For example, with a shift of 1, A would be replaced by B, B would become C, and so on. The method is named after Julius Caesar, who allegedly used it to communicate with his generals. For example: Input: "defend the east wall of the castle" Output: "efgfoe uif fbtu xbmm pg uif dbtumf" Write a program that encrypts the user input using the Caesar cipher. */ //First time i am trying to solve an assignment.Any suggestions are welcome. #include #include using namespace std; int main() { string str; getline(cin,str); int len=str.length(); for(int i=0;i<=len;i++) { switch(str[i]) { case 'a': cout<<"b"; break; case 'b': cout<<"c"; break; case 'c': cout<<"d"; break; case 'd': cout<<"e"; break; case 'e': cout<<"f"; break; case 'f': cout<<"g"; break; case 'g': cout<<"h"; break; case 'h': cout<<"i"; break; case 'i': cout<<"j"; break; case 'j': cout<<"k"; break; case 'k': cout<<"l"; break; case 'l': cout<<"m"; break; case 'm': cout<<"n"; break; case 'n': cout<<"o"; break; case 'o': cout<<"p"; break; case 'p': cout<<"q"; break; case 'q': cout<<"r"; break; case 'r': cout<<"s"; break; case 's': cout<<"t"; break; case 't': cout<<"u"; break; case 'u': cout<<"v"; break; case 'v': cout<<"w"; break; case 'w': cout<<"x"; break; case 'x': cout<<"y"; break; case 'y': cout<<"z"; break; case 'z': cout<<"a"; break; case ' ': cout<<" "; break; default : break; } } }
