#19 C Arrays | C Programming For Beginners
In this video, you will learn about array in C Programming. You will learn to declare, initialize and access elements of an array with the help of examples. In addition to that you will have clear concept on using array with loops and index out of bound errors that you may face while using an array.

Awesome and crisp explanation. Keep making more videos to cover the entire language. Your series is really very crisp ,informational and easily understandable.

[@hrushikeshtodkari5265]

I Like your teaching method. keep posting such contents free for the student. thank you.....

[@olusamuel7672]

The Quiz answer is 0, no digit is stored in that index so automatically it's 0. Between I love the way you teach, you make C look easy and have really really learnt a lot from your channel. good job ❤😊

[@JoseCarv0]

Yes, it is 0, but the reason is not that.

[@galaxygaming8109]

sok tau kau deck

[@ravikumarronad7475]

Correct Answer is C. 0 Array of size is 5 so in the given array have 3 elements so remaining 4th and 5th index number store automatically 0 value. Pictorial is: Int num[5]= { 2, 3, 5, 0, 0} Important Note: Array is Collection of Homogenous elements.

[@akashmathdevru8618]

no it show random no....because in video saw put value 6 nut it can present 0--4 integer remaining it get random no. so i think D

[@TiTan-gr3pv]

​@@akashmathdevru8618in that case the value she asked for was out of the size of the array so it gave a random value but if you don't store any value willingly inside a particular index of an array the value 0 will be stored in many compilers and some may show an error so it doesn't give an output of a random value

[@bansarithakker7661]

Thnx broo

[@ntwadumela7]

Good but its good programming practice that you initialize avg as int avg and then add avg=sum/5 and print it.

[@andrewsterling895]

I suggest you remove the printf("Entre the marks "); out of the for loop.

[@josuealcala6255]

I appreciate this. I missunderstood the wording of the quiz and this made me understand what she was asking for

[@stealthy_doctor]

wonderful explanation, i think the answer to the quiz is C. 0 and for the task: #include #include int main() { // Write C code here int age[6]; int sum; int average; printf("Enter 5 Subject's Grades: "); for(int i =0;i

[@fairooznadia8955]

[@thisistusharmahajan]

0

[@maybevinay]

Answer:- 0

[@user-gv9if4jx3h]

Garbage Value

[@rickzalman4136]

0 is the default value for any element not initialized by the user

[@codewithabhi1089]

0 will be the answer bcz size is exceeding the array.
