Question:C program for hexadecimal to binary conversion
Answer
#include<stdio.h> #define MAX 1000 int main(){ char binaryNumber[MAX],hexaDecimal[MAX]; long int i=0; printf("Enter any hexadecimal number: "); scanf("%s",hexaDecimal); printf("\nEquivalent binary value: "); while(hexaDecimal[i]){ switch(hexaDecimal[i]){ case '0': printf("0000"); break; case '1': printf("0001"); break; case '2': printf("0010"); break; case '3': printf("0011"); break; case '4': printf("0100"); break; case '5': printf("0101"); break; case '6': printf("0110"); break; case '7': printf("0111"); break; case '8': printf("1000"); break; case '9': printf("1001"); break; case 'A': printf("1010"); break; case 'B': printf("1011"); break; case 'C': printf("1100"); break; case 'D': printf("1101"); break; case 'E': printf("1110"); break; case 'F': printf("1111"); break; case 'a': printf("1010"); break; case 'b': printf("1011"); break; case 'c': printf("1100"); break; case 'd': printf("1101"); break; case 'e': printf("1110"); break; case 'f': printf("1111"); break; default: printf("\nInvalid hexadecimal digit %c ",hexaDecimal[i]); return 0; } i++; } return 0; }Sample output: Enter any hexadecimal number: 2AD5 Equivalent binary value: 0010101011010101
