C Program to implement the Lagrange interpolation. Lagrange interpolation is the polynomial interpolation. It is the process of passing a polynomial of degree n-1 through n points. In this program we used the arrays in c.

C Program to check the given number is perfect or not?. Perfect number is a positive integer that is equal to the sum of its proper positive divisors. example 6, divisor of 6 are 1, 2,3. Sum of divisors is 1+2+3=6. Read more about C Programming Language . /************************************************************ You can use all the programs …
Pascal’s Triangle is a triangular array where each number is the sum of the two numbers directly above it. Row n, column k holds the binomial coefficient C(n,k) — the number of ways to choose k items from n. It appears in combinatorics, probability, the binomial theorem, and polynomial expansion. The C program below builds …
Floyd’s triangle in C is a right-angled triangular arrangement of consecutive natural numbers. Row 1 contains 1 number, row 2 contains 2, row 3 contains 3, and so on. It is named after Robert W. Floyd, who used it to teach loop control and nested iteration. The total numbers through row n is 1 + …
Measuring program execution time in C helps you benchmark algorithms and quantify how long different approaches take. The standard tool is the clock() function from <time.h>, which measures CPU time consumed by the program — not wall-clock time. Two snapshots (before and after) divided by CLOCKS_PER_SEC give you the elapsed time in seconds. clock() and …
Shell sort is a generalization of insertion sort that sorts elements far apart before sorting adjacent ones. Invented by Donald Shell in 1959, it repeatedly applies insertion sort on sublists of decreasing “gap” sizes until the gap reaches 1 — at which point one final insertion sort on the nearly-sorted array runs in near-linear time. …
