How to convert binary to decimal

Binary to decimal converstion program given code below:

We know that binary digit have only two bit '0' or '1' bit for executing all operatin in computer.

if let have a binary digit : 1011001 

than what will be out of the given binary code in decimal

than follow given code to convert in decimal

#include<stdio.h> #include<conio.h> #include<math.h> // vikasstudyknowledge.blogspot.com void main(){ int decimal=0,weight=0, rem; unsigned long int binary, bin; printf("Enter binary number\n"); scanf("%ld",&binary); bin = binary; while(binary != 0){ rem = binary%10; decimal = decimal + rem*pow(2,weight); binary = binary/10; weight++; } printf("%ld is converted into decimal is : %d",bin,decimal); getch(); }

Intersection operation perform in c programming

if set A = {2,5,6} and set B = {3,5,2,6}

Than Intersection of A and B is intersection = {2,5,6}

Output of the intersection operation

This code to perform Intersection operation in C programming 👇👇👇

#include<stdio.h> int removerepeated(int size,int a[]); void sort(int size,int a[]); main(){ int i,size1,size2,size,j=0,k,intersectionsize; printf("Enter size of an array1\n"); scanf("%d",&size1); printf("Enter size of an array2\n"); scanf("%d",&size2); int a[size1],b[size2]; if(size1<size2){ intersectionsize=size1; }else if(size1>size2){ intersectionsize=size2; }else{ intersectionsize=size1; } int intersection[intersectionsize]; // Intersection array printf("Enter numbers for array 1\n"); for(i=0;i<size1;i++){ scanf("%d",&a[i]); } printf("Enter numbers for array 2\n"); for(i=0;i<size2;i++){ scanf("%d",&b[i]); } //Intersection starts k=0; for(i=0;i<size1;i++){ for(j=0;j<size2;j++){ if(a[i]==b[j]){ intersection[k]=a[i]; k++; } } } //Sorting sort(k,intersection); //Removing size=removerepeated(k,intersection); printf("Array after intersection\n"); if(size>0){ for(i=0;i<size;i++){ printf("%d\n",intersection[i]); } }else{ printf("No intersection\n"); } } int removerepeated(int size,int a[]){ int i,j,k; for(i=0;i<size;i++){ for(j=i+1;j<size;){ if(a[i]==a[j]){ for(k=j;k<size;k++){ a[k]=a[k+1]; } size--; }else{ j++; } } } return(size); } void sort(int size,int a[]){ int i,j,temp; for(i=0;i<size;i++){ for(j=i+1;j<size;j++){ if(a[i]>a[j]){ temp=a[i]; a[i]=a[j]; a[j]=temp; } } } }

Union Operation perform in c programming

if set A = {2,5,6} and set B = {3,5,2,6}

Than union of set A and B is Union = {2,3,5,6}

Output of the Union operation

This code to perform Union operation👇👇👇

#include<stdio.h> // This is header file int removerepeated(int size,int a[]); // Function initiolize void sort(int size,int a[]); main(){ // Main block int i,size1,size2,size,j=0,k; printf("Enter size of an array1\n"); scanf("%d",&size1); printf("Enter size of an array2\n"); scanf("%d",&size2); int a[size1],b[size2],uni[size1+size2]; printf("Enter numbers for array 1\n"); for(i=0;i<size1;i++){ scanf("%d",&a[i]); } printf("Enter numbers for array 2\n"); for(i=0;i<size2;i++){ scanf("%d",&b[i]); } //union start for(i=0;i<size1;i++){ uni[j]=a[i]; j++; } for(i=0;i<size2;i++){ uni[j]=b[i]; j++; } //Sorting fuction call sort(size1+size2,uni); //Remove repeated elements fuction call size=removerepeated(size1+size2,uni); printf("Array afetr Union \n"); for(i=0;i<size;i++){ printf("%d\n",uni[i]); } } //Sorting fuction define void sort(int size,int a[]){ int i,j,temp; for(i=0;i<size;i++){ for(j=i+1;j<size;j++){ if(a[i]>a[j]){ temp=a[i]; a[i]=a[j]; a[j]=temp; } } } } // remove repeated value fuction define int removerepeated(int size,int a[]){ int i,j,k; for(i=0;i<size;i++){ for(j=i+1;j<size;){ if(a[i]==a[j]){ for(k=j;k<size;k++){ a[k]=a[k+1]; } size--; }else{ j++; } } } return(size); }
