cstructVector, C (gcc)

Language: Layout:

//gcc 7.4.0
//define a structure to represent a vector of integer values and write a modular program to perform the following tasks: create a vector, modify the value of a given element,multiply by a scalar value, display the vector in a sorted way(least to great)

//this code is created by Rezaul Hoque on August 20,2021;contact: jewelmrh@yahoo.com

//note: codes shared by Rezaul Hoque on rextester are not for sale; they are created and shared to facilitate the algorithm learning process; many like Hoque use this platform to practice programming ;Rezaul hopes his contribution helps others to fine tune their learning;
