From the C Standard (6.4.5 String literals) 7 It is unspecified whether these arrays are distinct provided their elements have the appropriate values. If the program attempts to modify such an array, the behavior is undefined. As for your statement. The second paragraph says that “C does not strictly prohibit modifying string literals” while compilers … Read more
For starters you could just run the code… but otherwise we can try and predict the output. For starters the function f has two parameters, i and j. The & Infront of the j means that the value of the function input is passed by reference (the value of the variable will be edited). So … Read more
