Lab programs

1Simple Calculator in CRead two numbers and an operator (+, -, *, /) and print the result, handling division by zero and unknown operators.
2Roots of a Quadratic Equation in CAccept the coefficients a, b and c of ax² + bx + c = 0 and print the roots, handling the linear case and the real, equal and complex root cases.
3Electricity Bill with Slab Rates and Surcharge in CRead a customer's name and units consumed, apply the slab tariff, add the meter charge and the 15% surcharge above Rs 400, and print the bill.
4Number Pyramid 1, 121, 12321 in CRead the number of rows n and print a centred pyramid in which row i counts up from 1 to i and back down to 1.
5Binary Search in CSearch for a key in a sorted array of integers using binary search and report its position, or that it is absent.
6Matrix Multiplication with Validation in CMultiply two matrices and check the multiplication rule first: the number of columns of the first matrix must equal the number of rows of the second.
7sin(x) and cos(x) Using Taylor Series in CApproximate sin(x) and cos(x) with Taylor series, combine them into sin(x)/cos(x), and compare each result with the library functions in math.h.
8Bubble Sort in CSort a list of N integers into ascending order using bubble sort, swapping adjacent elements that are out of order.
9String Length, Compare and Concatenate Functions in CWrite your own functions for string length, comparison and concatenation that receive their strings through pointer parameters, and use them on two input words.
10Student Marks Using Structures in CStore each student's name and marks in a structure, compute the class average, and list the students who score above and below it.
11Sum, Mean and Standard Deviation Using Pointers in CUse pointers to walk an array of n real numbers and compute their sum, mean and standard deviation.
12Copy a Text File in CRead a source file name and a target file name, copy the source file character by character into the target, and report errors when a file cannot be opened.
