Thank you mam for helping middle class students who can't afford coaching.

total elements = 14 i.e(2x7=14)
size of float in c = 4
total size for this array = 14x4=56 bytes

total elements = 28 i.e(4x7=28)
size of int in c = 4
total size for this array = 28x4=112 bytes

Madam, I wanted to let you know that your lecture was exceptionally insightful.
Your unique approach and examples really resonated with me, and I found it extremely helpful.
Thank you for such a great class!!

One problem i have always had is that those who understand something are unable to explain it in a way that I can understand.But that problem is no more since I came here.Good work.Much love from kenya🇰🇪

please complete C programming mam.dont leave it incomplete because पूरे यूट्यूब पर सिर्फ आपका लेक्चर ही समझ आता है मुझे अगर आप बंद कर दोगी तो फिर मैं कभी सीख नही पाऊंगा।

If there may any Award by YouTube for Best Teacher.... It may goes to you
Thank You Ma'am 🙏

total elements = 14 ;
size of float in c = 4 ;
total size for this array = 56 byts ;

[saishashi]

Total elements = 2 rows * 7 columns = 14 elements
float size = 4 bytes
total bytes 4*14 = 56 bytes

[abdulkarimshaikh]

For float mark[2] [7];
Bytes are: 56
For int a[4] [7];
Bytes are: 112

[ezekielsamuel]

you are a gifted your explanation is superb and easy to comprehend

[tops]

For float mark[2] [7];
total elements: 14
Bytes are: 56
For int a[4] [7];
total elements: 28

Bytes are: 112

Thank you mam for helping middle-class students who can't afford to coach. 😊

[maryannemuthoni]

float a[2, 7] can store 14 elements and they will take 56 bytes.
Checked on IDE you can declare array of floats

int a[4, 7] can store 28 elements and they will take 112 bytes.

[Aptitude_guide]

Float can store here=>2×7=>14 elements
Size of float type array is=Sizeof(float)×14

[hariparuchuru]

Total Elements we can store are 2X7 = 14
Size Allocated is 14X4 = 56
since Size of Float is 4 bytes

[SatyamSharmabcebgp]

Maim answer of last question is total no of elements are 14 and no of byte allocated are 56.( Because no of elements in 2d array= m×n where m is row size and n is column size and no of byte allocated is = total no of elements in 2d array × size of data type that we use.

[Msd]

float a[2][7]:-
✓Size of array or no of elements
= 2*7=14
✓it should allocate 14*4=56
Int a[4][7]:-
✓4*7=28 elements
✓28*4=112bytes

[Fallforme]

mam is so beautiful that i forget learning c and started focusing on philosphy(how someone have everything looks, brain etc, is it in unfair)

[badarmunir]

Size of array=28
Memory allocated = 112 byte.

kal yehi pane wale hain class mai...I studied it in advance👍☺️
