How high is the requirement for mathematics to learn C language or real programming?
If the language itself is concerned, the requirements for mathematics are not high, because beginners are only based on one language level, and if supplemented by data structures, they will achieve good results.
In other words, if you enter the IT software industry, because it involves the design of many algorithms, the requirements for mathematics are relatively high. But it doesn't prevent you from understanding and using this language.
