Q1 Write a C program that will swap any two nibbles of a long int x (64-bit integer) A nibble is a four-bit aggregation. There are two nibbles in a byte. For this problem the index of the least significant nibble is 0, and the index of the most significant nibble is 15 (so 0 -), loops, switches, function calls, macros, conditionals (if or ?: You are allowed to use all bit level and logic operations, left and right shifts, addition and subtraction, equality and inequality tests, integer constants (
