size_t c = sizeof(7); size_t d = sizeof(3.234); size_t e = sizeof a; The result of the sizeof operator is of a type called size_t, which is defined in the header file <stddef.h>. size_t is an unsigned integer t
The parametersize_t sizespecifies the number of bytes to allocate. It is an unsigned integer type, ensuring that only non-negative values are passed as the size. Importance of stdlib.h To usemalloc(), one must include the header filestdlib.hin their C program. This header file contains the...

This explains the weird result above: by doing `ioc.c = 'c'`, // we wrote over part of our integer! We can see this in more detail by printing the bytes: unsigned char * bytes = (unsigned char *) &ioc; printf("Bytes of ioc: %d %d %d %d\n", bytes[0], bytes[1], bytes[...
In cases where the results exceed the original range, these functions clamp the result values back to the valid range. E.g. the maximum positive value for a 16-bit unsigned integer is 32767. A multiplication operation of 4 * 10000 = 40000 would exceed this range. The result would be clam...
