To make it work rewrite the code as follows – The code above will work. In C, when you wish to change the value of a variable in a function, you “pass the Variable into the function by Reference“. You can read more about this here – Pass by Reference Now the error means that … Read more
To answer the question without reading too much else into it i would You could use the second line in a loop with what ever other string operations you want to keep using char’s as strings.
I am extremely new to programming and I am having problems with the basic starting program of, ‘hello, world’. I have downloaded MinGW and I believe I set it up correctly with the command promt by entering: setx PATH “%PATH%;C:\MinGW\bin” Then I created this code following a guide while using Notepad++ saving it under c:/code/c/hello.c … Read more
If you don’t specify a target on the command-line, Make uses the first target defined in the makefile by default. In your case, that is makefile:. But that doesn’t do anything. So just remove makefile:.
You can not have static array which size is given as a variable That’s why constants should be #defined: This way preprocessor will replace a with 6, making it valid declaration.
In C, int, char, long, etc. are all integers. They typically have different memory sizes and thus different ranges as in INT_MIN to INT_MAX. char and arrays of char are often used to store characters and strings. Integers are stored in many types: int being the most popular for a balance of speed, size and … Read more
The short answer is, edge-triggered means that you get notified only when the event is detected (which takes place, conceptually, in an instant), while level-triggered means you get notified whenever the event is present (which will be true over a period of time). For example, in an edge-triggered system, if you want a notification to … Read more
The ~ operator is bitwise NOT, it inverts the bits in a binary number:
I’m trying to write a program that can compare two files line by line, word by word, or character by character in C. It has to be able to read in command line options -l, -w, -i or –… if the option is -l, it compares the files line by line. if the option is … Read more
A floating point number is normalized when we force the integer part of its mantissa to be exactly 1 and allow its fraction part to be whatever we like. For example, if we were to take the number 13.25, which is 1101.01 in binary, 1101 would be the integer part and 01 would be the fraction part. I could represent 13.25 as 1101.01*(2^0), but this isn’t normalized because the … Read more
