Explore how a computer works—from the CPU and RAM to hard disk and operating system—distinguishing programs from data and comparing compiler and interpreter languages.
Learn how to craft valid C expressions using precedence and associativity. Apply formulas for area, perimeter, arithmetic progression, and quadratic roots through correct expression syntax.
Explore recursion by defining it, examining base conditions, and tracing function calls, while understanding stack memory, time complexity, and recurrence relations.
Analyze time complexity from recurrence relations and graphs, comparing constant, logarithmic, linear, linear-log, quadratic, and exponential costs to evaluate recursive algorithms.
Explore factorial in C via recursion, using base case 0! = 1 and N! = N multiplied by (N minus 1)!, then compare with a loop.
C programming is a general-purpose, procedural, imperative computer programming language developed in 1972 by Dennis M. Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system. C is the most widely used computer language. It keeps fluctuating at number one scale of popularity along with Java programming language, which is also equally popular and most widely used among modern software programmers.
