I'm a beginner programmer. And i wanna to know how should use these programs in real life usses?
Quite a lot, actually, if you use the programming to manage various machines. Google's self driving car, for example, relies a lot on programming, especially C and C++. But also factory machinery for mass production or even vegetable production improves through programming and computers. With vegetables, for example, a digital camera and additional software algorithms can evaluate the quality of each piece of food within a fraction of a second and thus decide if it is fit for human consumption or if it has a weird spot and thus becomes fodder for cattle.
