pick one????????????

Question

//both are c++ codes try to initialize an array freqs[11] to zeros
//for futur arithmetic calculation
int freqs[11]={0,0,0,0,0,0,0,0,0,0,0};//way 1

//or
int freqs[11];
for(int i=0;i<=10;i++){
freqs[i]=0;
}//way 2
//yes i agree way 2 is much much easier but a loop needs more time to process than direct manipulation

Answer 1

i agree with krish. just set element 1 (freqs[0]) to 0. but if for some reason you NEED all set to 0, then it would depend on the size of the array. for a small array i would use the first method, but for one with hundreds of elements, i would use the second!

Answer 2

The loop should be used if the array is larger than you can 'manually initialize'.

Use the manual way (int freqs[11]={0,0,0,0,...}) for readability unless there is a possibility that you may one day create a larger 'freqs array'.

The time it takes to process is negligible and you shouldn't worry about that unless you are pushing the limits with game programming. Always choose readability over speed.

Answer 3

actually we can write first one with
int freqs[11]={0}
will make all elements zero

Answer 4

for(int i=0;i<=10;i++){

Answer 5

the second one:
for(int i=0;i<=10;i++){

Answer 6

surely, the second one.
