In C, string operations cannot have a convenient interface, because of memory management. If a function receives a string, and converts it to another string, you should decide how to declare its interface. The simplest interface is in-place (strtok uses it); you can use it only if the output is somehow smaller than input: void … Read more
After reviewing your updated question, what I think you really want is a function that will accept a template and an object of values to replace with. Here’s a working example. function PropertyAccess(template, values) { for (key in values) { template = template.replace(‘${‘ + key + ‘}’, values[key]) } return template; } console.log(PropertyAccess(‘hello ${val}’, {val: … Read more
What is the difference between char *exp=”a+b” and char exp[]=”a+b”? Are they stored the same way in memory or they differ? solved What is the difference between char *exp=”a+b” and char exp[]=”a+b”? Are they stored the same way in memory or they differ?
Make the arrays static so they will not be allocated on the stack. static const char fetch[] = “fetch”; static const char push[] = “push”; static const char quit[] = “quit”; solved How to use string literals without using arrays and #define preprocessor directive?
The type of foo is char[4], i.e. a character array containing 4 chars (including the trailing null character ‘\0’.) String literals can be used to initialize character arrays. If an array is initialized like char str[] = “foo”;, str will contain a copy of the string “foo”. The type of bar is char *, qux … Read more
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
