I hope I helped him become more modern/

What is worse is because this rule exists it means it happens often :/

How long do you think it takes to unlearn bad practises and write "good" C++ code?

Just a rough estimate

I don't know, I think it's an ongoing process, since C++ keeps evolving as well. Just try to stay up to date and try to use the language as it is designed to be used.

gotcha, thanks!

Can anyone help me to write program to convert binary to decimal using array (Can use recursion also)

Write a C program to convert a binary number to decimal with the help of the function int toDecimal (char bits[], int length) where bits is the character array to represent bits of binary numbers and length is the number of bits in the binary number.

How can i scan any binary number instead of 100 in char bstr[]= "100";

Google ascii

Also, strlen returns a size_t, so it might be better to use a size_t and not an int.

(Of course then the for loop would have to use size_t counters)

#include <stdio.h> void main() { int i,j,m,n,o,p; printf("Enter the no. of row and column of 1st matrix"); scanf("%d%d",&m,&n); printf("Enter the no. of row and column of 2nd matrix"); scanf("%d%d'",&o,&p); if(m==o && n==p) { int a[m][n]; printf("Enter the first matrix"); for(i=0;i<m;i++) { for(j=0;j<n;j++) { scanf("%d",&a[i][j]); } } int b[m][n]; printf("Enter the second matrix"); for(i=0;i<m;i++) { for(j=0;j<n;j++) { scanf("%d",&b[i][j]); } } int sum[m][n]; for(i=0;i<m;i++) { for(j=0;j<n;j++) { sum[i][j]=a[i][j]+b[i][j]; printf("%d\t",sum[i][j]); } printf("\n"); } } }

How can i add function for this program

Function is add(a[],b[],int m,int n)

What do you have trouble with? Function syntax? Something else?

Nop I have to add function for my assignment

I tried but got some errors

I also dont know what i did

Well, as you can read the rules, we won't do the assignment for you. You can provide us tour code and we can help you fix it though.

This is code

I am beginner so dont know much

Please post code into a snippet website like ideone.com or wandbox.org

Wow That's a lot of Rust features

Pattern matching

It's a fucking incredibly

Wow That's a lot of Rust features

U drunk?

C++ is great

U drunk?

Forbidden

U drunk?

Pattern matching

It's in Rust

Forbidden

OK

But I didn't get what reflections are!!

Pattern matching

So

It's in Rust

And?

So

Yeah, That's great

How old is Rust?

How old is Rust?

4 years since the first stable release

Rust is pretty new.

Conpared to C++'s age it's a baby.

With that Rust can kiss C++ ass

Good baaa

Good baaa

I wonder whether Rust will even be close to as influential as C++ was/is.

Shaun the sheep

I wonder whether Rust will even be close to as influential as C++ was/is.

Will have to wait until big projects come up. Meanwhile, everything is just speculation

All are humans here??

No, there are some bots.

Any one pls help me To write program for to find even and odd number

If(n%2==0)

What this statement says

Help me to solve this error please

Split statement on line 8 to 2. char *temp; temp = malloc(sizeof(char) * 2);

Split statement on line 8 to 2. char *temp; temp = malloc(sizeof(char) * 2);

#include <stdio.h> #include <stdlib.h> #include <math.h> #include <string.h> int main() { char c[1000]; char* temp = (char*)malloc(sizeof(char) * 2); int i = 0, sum = 0, j = 0; printf("Enter the binary number:"); scanf("%s", c); int len = strlen(c); for (i = (len - 1); i >= 0; i++) { temp[0] = c[j]; sum = sum + (atoi(temp) * pow(2, i)); j++; } printf("The decimal number is:%d", sum); }

Output dont come but program runs

You have an error btw

Add temp[1] = 0; somewhere before atoi

Add temp[1] = 0; somewhere before atoi

Inside for loop or outside

No matter

Inside for loop or outside

Hello .. There is simple bug :O Just in loop Don't increment i decrement it i--

Still no output

Check this once

Increment j++ Decrement i--

#include <stdio.h> #include <stdlib.h> #include <math.h> #include <string.h> int main() { char c[1000]; char* temp= (char*)malloc(sizeof(char) * 2); int i = 0, sum = 0, j = 0; printf("Enter the binary number:"); scanf("%s", c); int len = strlen(c); for (i = (len - 1); i >= 0; i--) { temp[0] = c[j]; sum = sum + (atoi(temp) * pow(2, i)); j++; } printf("The decimal number is:%d", sum); }

Try this code 👌

Increment j++ Decrement i--

True

Thnks guys

Need to add function insame code now

Function having argument char bits[]and int length

Well I said stable, not how old Rust!!!

I hear a lot about reflections in the upcoming versions of C++
