Question

Write C program : Enter N and N pairs of positive integer pairs, convert each pair of positive integers into binary and add, and output the formula. Decimal to binary function prototype: int DecToBin(int integer);

The range of input N is 1 <= N <= 100, and the range of positive integers input is 0 < n <= 255. The output format is %08d. If the entered N or positive integer is out of range, "Invalid input" is output. If a positive integer pair is entered more than N pairs, the multi-input portion is not processed.

Answer 1

#include

  

void decToBinary(int n)

{

// array to store binary number

int binaryNum[32];

// counter for binary array

int i = 0;

while (n > 0) {

// storing remainder in binary array

binaryNum[i] = n % 2;

n = n / 2;

i++;

}

// printing binary array in reverse order

for (int j = i - 1; j >= 0; j--)

printf("%d",binaryNum[j]);

}

int main(){

int n1,n2;

scanf("%d",&n1);

scanf("%d",&n2);

if( n1<1 || n1 >100 || n2<1 || n2 > 100){

printf("Invalid Input");

}

else {

printf("The Binary equivalent is : ");

decToBinary(n1);

printf("The Binary equivalent is : ");

decToBinary(n2);

printf(" Sum is : %d",n1+n2);

}

return 0;

}
