Explanation / Answer

#include <stdio.h>
#include <string.h>

int main()
{
double firstN, secondN;
char op;
char ch[20];
do{
  
printf(" Type a number, operator, number -- seperated by a space: ");
scanf("%lf %c %lf", &firstN,&op,&secondN);
  
if(op=='+'){
printf("%lf + %lf = %lf", firstN,secondN,(firstN + secondN) );
}
else if(op=='-'){
printf("%lf - %lf = %lf", firstN,secondN,(firstN - secondN) );
}
else if(op=='*'){
printf("%lf * %lf = %lf", firstN,secondN,(firstN * secondN) );
}
else if(op=='/'){
printf("%lf / %lf = %lf", firstN,secondN,(firstN / secondN) );
}
else
{
printf(" Unknown operator");
}
printf("Do you want to continue (Yes/No)");
scanf("%s",ch);
  
if(!(strcmp(ch, "Yes") ==0))
