/* Program: Write a program to illustrate the results of type conversion between signed and unsigned long and short integer data types. Author: www.atnyla.com */ #include "stdio.h" int main() { short int si; long int li; unsigned short int usi; unsigned long int uli; si = -10; li = si; /* sign extension - li should be -10 */ printf("si = %8hd li = %8ld\n",si,li); usi = 40000U; /* usigned decimal constant */ uli = usi; /* zero extension - uli should be 40000 */ printf("usi = %8hu uli = %8lu\n",usi,uli); uli = 0xabcdef12; /* sets most bits ! */ usi = uli; /* will truncate-discard more sigficant bits */ printf("usi = %8hx uli = %8lx\n",usi,uli); si = usi; /* preserves bit pattern */ printf("si = %8hd usi = %8hu\n",si,usi); si = -10; usi = si; /* preserves bit pattern */ printf("si = %8hd usi = %8hu\n",si,usi); return 0; }
Output:
si = -10 li = -10 usi = 40000 uli = 40000 usi = ef12 uli = abcdef12 si = -4334 usi = 61202 si = -10 usi = 65526 Press any key to continue . . .
