Using format specifiers for signed integers

Signed integers include integers that can have negative as well as positive values. The next example program is signedInt.c, and it begins as follows:

#include <stdio.h>

int main( void ) {

  int smallInt = 12;

  int largeInt = 0x7fffffff; // int32 max

  int negativeInt = -smallInt;

  unsigned anUnsigned = 130;

  long long int reallyLargeInt = 0x7fffffffffffffff; // int64 max

  // the other code snippets go here.

}

The values of smallInt, largeInt, negativeInt, anUnsigned, and reallyLargeInt will be printed using various fields, precision, and alignment modifiers. Notice that largeInt is given a hexadecimal value that is the largest positive value a 32-bit integer can hold. Likewise, reallyLargeInit is given a hexadecimal value that is the largest positive value a 64-bit...
