[psycos_]

SIR MAZA AGYA, YOU'RE LITERALLY SUCH AN AMAZING TEACHER!!! ❤

[QuickEnglishSnippet]

1:56:00 we can also use another method which is called as upper triangle way.
in second loop, we can add a condition if(j>i) then only swapping occurs otherwise loops continues, i think this method is much more simpler and easy to understand. thankyou sir for this amazing lecture.❣

[divyanshujaiswal]

Rest of 10 hour tutorial for whole c language rest in piece after seeing this much effort. Pw rocks always 🙂💐

[Shrezal]

sir i don't how to show you enough gratitude but genuinely thankyou so much.

[ARUNKUMAR-zrfq]

Maza aa gya sir. Bahut badhiya lecture hai. Ab itna confidence aa gya hai ki lag rha rha hai apne batch me main hi top karunga.

[verdatfatima]

2:05:27 We can also do this by another method which is more easy to understand
include<iostream>
using namespace std;
int main(){
int n;
cout<<"Enter num of row and coloumb :";
cin>>n;
int arr[n][n];
cout<<"Enter all elements "<<endl;
for(int i=0;i<n;i++){
for(int j=0;j<n;j++){
cin>>arr[i][j];
}
}
//transpose
for(int i=0;i<n;i++){
for(int j=i;j<n;j++){
int temp=arr[i][j];
arr[i][j]=arr[j][i];
arr[j][i]=temp;
}
}
cout<<endl;
//rotate
for(int i=0;i<n;i++){
for(int j=0;j<n;j++){
cout<<arr[i][n-j-1]<<" ";
}
cout<<endl;
}
return 0;
}

[samimsk]

Dear Sir, Please make more chapter tutorials on Dynamic memory, Structure, and File Handling. Thank U :)

[ShriyashPatil]

Thank you sirji, mast lectures banaye hai apne!

[gracychauhan]

Sir I don't have words to explain your efforts . Hats off to youuu . may you leads toward growth and success in your life.. so much respect to you sir God bless you

[YashSharma-tfyu]

Maza a gaya...sir mind blowing explainations best on youtube sir.
Respect++;

[anshulsharma]

Raghav bhaiya or PW team ko teh dil se Shukriya...❣️

[ishayay]

finally i get the best channel for my pps subject sir you explained in very clr way thank you sir

[pri]

Sir in question 8, we can also change a[i][j] to a[j][i] as it'll directly give output without even using temp or using swap method.

[M_junaid_Kadri]

best tutorial of c in youtube ever as per my opinion .i'll try many of tutorials but the logic building learn from only this series lectures 👌👌👌👌

[Remainproductive]

The question on 45.24 sec
Why sir solve this with the worst method ever
Just write another line in the for loop that arr[i][j]=10 and done with the required answer
Thanks a lot sir aapki wajah se thora bahut samjh me aane laga hai

[anilkumar_]

Super super excellent explanation sir you are the best coding teacher in the youtube ❤❤👏👏👏🙏🙏

[AjEEtSinGH_]

3:15:8, we can also print in that loop itself, there's no point is using in using another loop
