The document contains 4 sets of questions related to C programming. Set I contains questions on flowcharts, C program structure, functions, pointers, arrays, structures, file handling and sorting. Set II contains questions on preprocessor, compiler, linker, control statements, arrays, functions, sorting and linked lists. Set III contains questions on algorithms, arrays, structures, file handling, sorting and stacks. Set IV contains questions on pointers, arrays, functions, sorting, linked lists and queues. The questions cover a wide range of topics in C programming including basic syntax, functions, pointers, arrays, structures, file handling, sorting and data structures.
