You need to check each case individually using the OR operator if you want to check more than one case. if (BothMods == “Yes” || BothMods == “YES” || BothMods == “yes”) { // do whatever } 4 solved c++ if specific words from string
The underlying problem here is that you don’t know in advance how many integers are going to come in, so you can’t use that for loop — there’s no sensible value for numbers. Instead, keep reading values until the end of the input: while (std::cin >> i) sum += i; When the attempted read eventually … Read more
The line World(height, width); constructs a temporary object and discards it. The member variable of the current object never get initialized properly. Simplify your code. Move the code to get input data to the function that calls it. For example, use it in main. int width = -1; int height = -1; cout << “Aby … Read more
When you write cin.ignore(0,’\n’), you’re saying “Ignore the characters in the stream until you have ignored 0 characters or you reach a ‘\n’”. Since you told the stream to ignore a maximum of 0 characters, it does nothing. When you write cin.ignore(100, ‘\n’), you’re saying “Ignore the characters in the stream until you have ignored … Read more
Try with g++ : g++ program.cpp -o a.out Or with gcc (If you add the c++ runtime library) : gcc program.cpp -o a.out -lstdc++ solved How to get an integer from user in c++? [closed]
Code: string myArray= “a, 0, 0, 0, 0, 0, 0, 0, 0”; int pushregister; cin >> pushregister; if (pushregister == a) { myArray = “a, 1, 0, 0, 0, 0, 0, 0, 0”; cout << myArray; } else { cout << “Wrong input” << endl; } return 0; 3 solved Using cin, if statement, and … Read more
int main() { string calculateagain = “yes”; do { //… Your Code cout << “Do you want to calculate again? (yes/no) ” cin >> calculateagain; } while(calculateagain != “no”); return 0; } Important things to note: This is not checked, so user input may be invalid, but the loop will run again. You need to … Read more
Both are same. fail is a typical function where is ‘!’ is an overloaded operator. You may want to check reference http://www.cplusplus.com/reference/ios/ios/fail/ before posting. 1 solved What’s the difference between cin.fail() and !cin in C++?
use cin.ignore(); before using getline() to empty the buffer.Read more here: When and why do I need to use cin.ignore() in C++? 1 solved Why code is jumping while inputting strings?
