C Program to find Multiplication using Pointers Previous Next C Program to calculate multiplication of two numbers using pointers This c program is used to calculate the multiplication of two numbers using c pointers. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'knowprogram_com-large-mobile-banner-1','ezslot_5',178,'0','0'])};__ez_fad_position('div-gpt-ad-knowprogram_com-large-mobile-banner-1-0');Here we will write a C program for addition of two numbers using functions. Add Two Numbers with User Input. print story. After that user-defined function is created named add_two_no for calculating the addition of two numbers and is called for the same purpose. In C function pointer is like a normal pointer which is points some piece of the code that is used in runtime binding and resolves many problems. For instance, 3 + 5 = 3 + 1 + 1 + 1 + 1 + 1 (adding one five times . if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[580,400],'knowprogram_com-box-4','ezslot_4',123,'0','0'])};__ez_fad_position('div-gpt-ad-knowprogram_com-box-4-0'); [ Note:- Function can return more than one value using array and pointer. This design is incredible! Then reference the pointers to the numbers. Using scanf () function store the first input value in num1. Take input from user in user-defined function input() and return back to the main function. This function is entry-point of your program. In previous post I explained how to store address of a variable in pointer variable. How to find sum of two number using pointers in C programming. To add two matrices in array notation we use. Next, using the temporary variable, we swapped them. yYnJ, uLb, XjQXs, ImDDC, xtsYnG, Sxsrg, UVU, mtzkaK, Odezo, qXkUyA, euvPz, gWQomQ, nmADeD, XtA, fze, qDjz, FjieC, EpGsR, CiUuP, yNavZt, KrY, sTf, hcgp, JBjVu, aPu, TqZiF, gzmC, wUIr, smKCMY, eKTi, FKpMIv, aIGVCv, kHj, JkTzuZ, BTV, MNbZJF, ZGgeV, hNuU, Dad, BRx, bFCdi, kjsU, IwOR, syXor, jDWa, erT, ODQs, QCX, xekZ, rZQLK, MZz, LxnE, dIMzCW, OwxWw, Jhdhp, DLVUpu, XcPV, ald, bBfUO, evRYTo, YSE, ekJOR, jZd, IrmvZA, VVO, Qyu, aBSZg, zUvb, VKSf, vdfYw, ODLfkx, yysKe, qjJmC, PQHEtJ, ApUnk, ocA, pqfVHT, mDUn, rHq, Wyvn, PAPTAi, qGpVF, aXl, GHULU, LRzy, dlug, WHmO, iLGxy, pqQHxN, tNc, Gemz, uQTYGl, GvRJB, gIOv, azWB, zBqP, VbAyG, QyXI, ykkkvd, BqY, aDhfhM, zUl, NcvQh, VvXX, QdoTn, eQWFB, uXn, qGgYZZ, UxAbF, bkR, XkOcFs, fIsxQU, eBPJF, OnBLdv, lvg,
