Code1 include int main int res1 res2 res printf Enter Value

Code1:

#include
int main(){
    int res1, res2, res;
  
   printf(\"\ Enter Value of Each Resistance 1: \");
   scanf(\"%d\", &res1);
   printf(\"\ Enter Value of Each Resistance 2: \");
   scanf(\"%d\", &res2);
   res = res1+res2;
   printf(\"\ Equivalent Series Resistance : %d Kohm\ \", res);

   return (0);
}

Code2:

#include
int main(){
    int res1, res2, res;
  
   printf(\"\ Enter Value of Each Resistance 1: \");
   scanf(\"%d\", &res1);
   printf(\"\ Enter Value of Each Resistance 2: \");
   scanf(\"%d\", &res2);
   res = (res1*res2)/(res1+res2);
   printf(\"\ Equivalent Parellel Resistance : %d Kohm\ \", res);

   return (0);
}

Take the two programs and combine them into a single program(using c not c++) that uses an if and else statement to calculate R total either in series or parallel based on the users preference (ask the users which way they want the resistance calculated).

Solution

main.c

#include<stdio.h>
int main(){
    int res1, res2, res,start;

   printf(\"Enter Value of Each Resistance 1: \");
   scanf(\"%d\", &res1);
   printf(\"\ Enter Value of Each Resistance 2: \");
   scanf(\"%d\", &res2);

   printf(\"\ Enter 0 to quite\ Enter 1 for series circuit\ Enter 2 for parallel circuit: \");
   scanf(\"%d\",&start);

if (start==0){
    return 0;
}
else if (start==1){
    res = res1+res2;
   printf(\"\ Equivalent Series Resistance : %d Kohm\ \", res);
}
else if (start==2){
res = (res1*res2)/(res1+res2);
   printf(\"\ Equivalent Parellel Resistance : %d Kohm\ \", res);
}
else {
    printf(\"Error!\");}
   return (0);
}
