Write an expression to detect that the first character of the userinput matches the firstletter.
sample program:
#include
#include
using namespace std;
int main() {
string userinput;
char firstletter = '-';
userinput = "banana";
firstletter = 'b';
if () {
cout < < "found match: " < < firstletter < < endl;
}
else {
cout < < "no match: " < < firstletter < < endl;
}
return 0;
}
print "censored" if user text contains the word "darn", else print userinput. end with new line.
sample program:
#include
#include
using namespace std;
int main() {
string userinput;
userinput = "that darn cat.";
return 0;
}
set haddigit to true if the 3-character passcode contains a digit.
sample program:
#include
#include
#include
using namespace std;
int main() {
bool hasdigit = false;
string passcode;
int valid = 0;
passcode = "abc";
if (hasdigit) {
cout < < "has a digit." < < endl;
}
else {
cout < < "has no digit." < < endl;
}
return 0;
}
replace any space ' ' by '_' in 2-character string passcode.
sample program:
#include
#include
#include
using namespace std;
int main() {
string passcode;
passcode = "1 ";
cout < < passcode < < endl;
return 0;
}
