How would you declare a string in c plus plus?
Examples: #include <iostream> #include <string> using namespace std; int main() { string st = "hello world!"; cout << st << endl; char c[] = "hello world!"; cout << c << endl; char a[13] = {'h','e','l','l','o',' ','w','o','r','l','d','!' }; cout << a << endl; char * s; s = ( char * ) malloc( 13 ); memset( s, 0, 13 ); s[0] = 'h'; s[1] = 'e'; s[2] = 'l'; s[3] = 'l'; s[4] = 'o'; s[5] = ' '; s[6] = 'w'; s[7] = 'o'; s[8] = 'r'; s[9] = 'l'; s[10] = 'd'; s[11] = '!'; cout << s << endl; free( s ); return( 0 ); }
What are the principal quantum number and the azimuthal quantum number in an atom of Potassium?

What is the context-free grammar for the language L an bm n, m 0?
The context-free grammar for the language L an bm n, m 0 can be represented as S - aSb .
What numbers that when you add it equals to30 but when you divided it by the smaller number the result is the smaller number?
Call the unknown larger number l and the unknown smaller number s. From the problem statement, l + s = 30 and l/s = s. From the second of these equations, after multiplying both sides by s, l = s2. substituting this value into the first equation yields s2 + s = 30, or s2 + s - 30 = 0. Factoring shows the latter expression to be equivalent to (s + 6)(s - 5) = 0, which is true when s = -6 or s = +5. The latter value of s leads to l = 25, which satisfies the conditions of the problem without negative numbers. The former value of s leads to l = 36, which also satisfies the conditions of the problem.
What subshell do the quantum numbers n equals 2 l equals 0 ml equals 0 describe?
The correct answer is 2s. n = 2 corresponds the 2nd energy level and l = 0 corresponds to the s-subshell. You did not need to know ml = 0 to get the answer
What is a quantum number set for Magnesium?
The quantum number for Sodium is this: 1s2 => n = 1 l= 0 m=0 s = +/- 1/2 2s2 => n=2 l=0 m= 0 s = +/- 1/2 2p6 => n = 2 ; l = 1 , m = -1 , 0 , +1 s = +/- 1/2 3s1 => n = 3 l=0 m=0 s = + 1/2
