How to alloc mem 20 floats?
Easy: 20 float = 20*4 bytes!
How to?
float *myfloat=(float*)malloc(sizeof(float)*20…
int *myint=(int*)malloc(sizeof(int)*20);
Now, how to handle that pointer?
if(myfloat){
scanf(“%f”,myfloat[1]);
bla_bla_bla();
free myfloat;
}
else{
printf(“Not enough memory”);
exit(1);
}
But, implementation in C++ is new operator.
Same as malloc:
float *myfloat=new[sizeof(float)*20];
And destrory with:
delete myfloat;
