A string is placed between quotes, while integers are not quoted. If a string is not quoted, the computer will read each word as a separate filename instead of being a single string.
std::string input = ""; std::getline (std::cin, input); // get input from stdin std::stringstream ss (input); // place input in a string stream integer num = 0; if (ss >> num) // extract integer from string stream { // Success! } else { // Fail! }
No. Any number that has a decimal place is not an integer. Even if the decimal place is ".0".
No, if it has a decimal place then its not an integer
It is a flag character that precedes the variable type place holder. %d %i Decimal signed integer. %o Octal integer. %x %X Hex integer. %u Unsigned integer. %c Character. %s String. See below. %f double %e %E double. %g %G double. %p pointer. %% %. No argument expected.

No. An integer is a WHOLE number. A number with a decimal place or a fraction is not an integer :)

82 is an integer and so is already rounded to more than just the tenths place. So the answer is 82.82 is an integer and so is already rounded to more than just the tenths place. So the answer is 82.82 is an integer and so is already rounded to more than just the tenths place. So the answer is 82.82 is an integer and so is already rounded to more than just the tenths place. So the answer is 82.
I believe Python's version of arrays is called dictionaries, although I am not completely sure and will have to check now...
You can certainly do that ... printf ("This is a number: 12345\n"); ... but that does not have the same value as placing the value in a variable and converting the variable into a string ... int i = 12345; printf ("This is a number: %d\n", i); That's the whole point of format specifiers - to initiate a conversion from one place to another.
