#include <iostream>
using namespace std;
#include <string.h>
class String{
private:
enum { SZ = 80 };
char str[SZ];
public:
String(){ strcpy(str, ""); }
String( char s[] ){ strcpy(str, s); }
void display() const{ cout << str; }
void getstr(){ cin.get(str, SZ); }
bool operator == (String ss) const{
return ( strcmp(str, ss.str)==0 ) ? true : false;
}
};
int main(){
String s1 = "yes";
String s2 = "no";
String s3;

cout << "\nEnter 'yes' or 'no': ";
s3.getstr();

if(s3==s1)
cout << "You typed yes\n";
else if(s3==s2)
cout << "You typed no\n";
else
cout << "You didn't follow instructions\n";
return 0;
}

#include #include #include #include void select(char *items, int count); int main(void) { char s[255]; printf("Enter a string:"); gets(s); select(s, strlen(s)); printf("The sorted string is: %s.\n", s); getch(); return 0; } void select(char *items, int count) { register int a, b, c; int exchange; char t; for(a = 0; a < count-1; ++a) { exchange = 0; c = a; t = items[ a ]; for(b = a + 1; b < count; ++b) { if(items[ b ] < t) { c = b; t = items[ b ]; exchange = 1; } } if(exchange) { items[ c ] = items[ a ]; items[ a ] = t; } } } design an algorithm for Selection Sort
