the rookie needs help again
-
I'm trying to do this project that reads a four word sentence from one string and then extract each word in the string to four other strings using the spaces between the words as indexes.Then display them in reverse. I cant seem to get this to work and I can't use coditional operators. Any suggestions.Here what I have so far.
#include #include using namespace std; int main(void) { string sentence; cout << "Enter a four word sentence:"; getline(cin,sentence); cout << "Original string:"<< sentence << endl; int blank=(" "); int firstindex = sentence.find(blank); string first = sentence.substr(0,firstindex); int secondindex = sentence.find(blank,firstindex + 1); string second = sentence.substr(blank + 1,secondindex); int forthindex = sentence.rfind(blank); string forth= sentence.substr(sentence.length,blank); int thirdindex= sentence.rfind(blank,forthindex - 1) string third= sentence.substr(thirdindex,sentence.length - 1); cout << "Reversed string:" << forth+" "+third+" "+second+" "+first<< endl;BINARY -

std::vector< std::string >to store the words one after another and thencoutthe strings using areverse_iterator?
"We trained hard, but it seemed that every time we were beginning to form up into teams we would be reorganised. I was to learn later in life that we tend to meet any new situation by reorganising: and a wonderful method it can be for creating the illusion of progress, while producing confusion, inefficiency and demoralisation." -- Caius Petronius, Roman Consul, 66 A.D.

no can't use anything other than what's there. find and rfind. BINARY

Use a
whileloop,rfindthe space,coutthe word and in the next roundrfindbeginning at the position before the last space. If you cant even use thewhileloop skip the lessons until you can...:-D
