C: warning: excess elements in array initializer; near initialization for ‘xxx’ ; expects ‘char *’, but has type ‘int’

While doing: puts the literal string in read-only memory and copies the string to newly allocated memory on the … Read more

Also, you don’t need to declare char class[30]; the longest string I see in your code is “undefined” so should be ok, 9 characters of “undefined” + 1 null terminating byte ‘\0’. And you should … Read more

Here is my code: when I type: 12345 6789 It gives me: 6789 Why I failed to save the 5 words char array ‘inp’ and it showed nothing? The second input looks normal though. However, when I set out[3] or out[5], it seems to work alright? It seem that two char array of [5] then … Read more
