void myfun (int *pi)
{
if (i==NULL) printf ("check failed");
}
One of the built-in datatypes.
no
No.
Converts a character to integer (if it is a numeric character)
An address in C or C++ is the location in memory of an object or function. An address is the contents of a pointer, as opposed to the contents of the memory location pointed to by the pointer.
Address of the allocated area, or NULL.
Address of the current object.
int * gred ; gred = new int [100] ; // this example snippet creates 100 ints
'int' is one of the built-in data-types, it is meant to hold integer values.
That is correct - In c plus plus you cannot assign integer value to enum - You can only assign an enum value to an enum. Even though an enum looks like an integer, it is not. It is an enum, and C++ implements strict type checking to reduce the probability of bad programming practices. enum ColorCode {black, brown, red, orange, yellow, green, blue, violet, grey, white}; ColorCode myColorCode; myColorCode = yellow; Even though yellow has an integer value of 4, you cannot say myColorCode = 4.
If A and B are multiples of C, then A + B is also a multiple of C: If A is a multiple of C then A = mC for some integer m If B is a multiple of C, then B = nC for some integer n → A + B = mC + nC = (m + n)C = kC where k = m + n and is an integer → A + B is a multiple of C
the size of an integer is determaind by using the function "sizeof(c)",here 'c' is any integer.
