Learn the magic in C.
Programmers can be roughly categorized into two. Hardworking, keyboard punching coders and smart working, always thinking coders. Both have irreplaceable importance in C programming and you’ll notice that in a team both are working hand in hand to finish the project. But it is worthwhile to sometimes exchange hats and learn the best from both.
C programming in general can give you problems that cannot be solved without a little bit of magic. Instances like this require you to try out some extremely useful programming tricks. Doing so can save you from bugs and annoying runtime errors. Many online courses offer useful tricks in C for free.
Top tricks used by C programmers revolve around the preprocessor level and smart usage of CPP. Offset Macro is yet another one used by seasoned programmers. The benefits of using cout and cin instead of scanf() removes the need to format specifiers, simple but effective this trick is used by C programmers who may have done a professional course in C programming and learned it there.
Let’s look at some magical hacks every C programming enthusiast should know to fall in love with this language all over again.`
Magical Hack#1 Use of a linker to compile multiple code files
A linker can be used to link vast number of files to produce one binary file which can be directly executed. A great trick for large programs, using a linker to compile multiple code files can hugely benefit you in saving time and efforts.
Magical Hack#2 Quick Commenting
In practise, one code is handled by numerous developers and may need a revisit even after it is deployed. In such a situation it makes sense to place comments alongside the code detailing out what a particular part of the code stands for. If done properly, quick commenting can make code maintenance simpler and can also help in finding and fixing bugs faster. Quick commenting is a magical hack that should be followed religiously to neatly document the code and the logic behind it.
If you want to sharpen your coding skills, there are many short term courses in C language than can help you scratch the surface and dig deeper into better programming.
Magical Hack#3 Smart Random Number Generator
Random number generators are often used in security related programs. In C, random number generation is defined by rand() function in the stdlib.h library. The function rand() returns a pseudo random number between 0 and RAND_MAX, which is the maximum value that can be returned by the function.
Magical Hack#4 Add Any Numbers Without “+” Operator
Adding two numbers without using an arithmetic operator is no less than magic. In C, one can easily achieve this by using the Half Adder logic. Adding can be done by performing XOR(^) of the two bits. Same can be applied for adding integers too.
Invest in your C skills
It’s a good investment to constantly learn new tricks and expand your command over C language. Even after finishing your classroom course, you can opt for bootcamp training course to add more weightage to your resume and impress recruiters.
