Write a program to half pyramid using 1 and 0 10101 01010 10101 01010 10101   Code: #include<stdio.h> int main(){ int i,j,n; printf("enter a number : "); scanf("%d",&n); for(i=1;i<=n;i++){ for(j=1;j<=n;j++){ if((i%2==0 || j%2==1)&&(i%2==1 || j%2==0)) printf("1"); else printf("0"); } printf("\n"); } } Output:

How to create WIFI Hotspot on ubuntu 18.04 laptop to create a WIFI Hotspot in ubuntu 18.04 , you should be first connect via lan. then follow just few steps step1:  click on the top right buttons and click on WiFi option and then click on WiFi setting click on WI-FI setting step2:  first "Turn on" your WIFI and them Click those "three lines" step 3: click on "Turn o WiFi Hotspot" option step4: click ok Turn on the Hotspot now active on your laptop. and you can see the password and network name . thank you. i hope you understand.

C program to Swap two Number Code: #include<stdio.h> void main(){ int n1,n2,temp; printf("enter two number :"); scanf("%d %d", &n1,&n2); temp=n1; n1=n2; n2=temp; printf("after swaping two number %d  %d\n",n1,n2); } Output:
