B) False.
13. True or false? If the new operator fails in itsattempt to allocate memory, the computer system aborts the programand prints an error message.
A) True.
B) False.
Explanation / Answer
7) you need to declare integer i. you have capital 'I'but lowercase 'i' needs to be declared. If that was simply atypo then the output is (there is a space after the lastvalue) 5 10 15 8) int alpha[3]={10,20,30}; 9) Arr[1] = 3 10) same as #7 on declaration, the output is however (there isa space after the last value) 500 400 300 200 100 11) int beta[5000]; 'Do whatever you want to fill it for(int i=0; i<5000; i=i+2) cout << beta[i] << " ";Related Questions
