Argument:
Return Value:
Remarks:
Example:
Output:
For ldiv(7, 3)
The quotient is 2 and the remainder is 1
For ldiv(7, -3)
The quotient is -2 and the remainder is 1
For ldiv(-5, 3)
The quotient is -1 and the remainder is -2
For ldiv(7, 7)
The quotient is 1 and the remainder is 0
For ldiv(7, 0)
The quotient is -1 and the remainder is 7
Explanation:
In the last example (ldiv(7,0)) the denominator is zero, the behavior
is undefined.
Allocates memory.
<stdlib.h>
void *malloc(size_t size);
size
Returns a pointer to the allocated space if successful; otherwise,
returns a null pointer.
malloc does not initialize memory it returns.
#include <stdio.h>
#include <stdlib.h> /* for malloc, free
int main(void)
{
}
Output:
Memory allocated
Memory freed
long *i;
if ((i = (long *)malloc(50 * sizeof(long))) ==
else
{
}
printf("Cannot allocate memory\n");
printf("Memory allocated\n");
free(i);
printf("Memory freed\n");
NULL)
number of characters to allocate
/* for printf, sizeof, */
/* NULL
