Using the C language, write a function that accepts two parameters: a string of characters and a single character. The function shall return a new string where the instances of that character receive their inverse capitalization. Thus, when provided with the character ’e’ and the string "Eevee", the function shall return a new string "EEvEE". Using the function with the string "Eevee" and the character ’E’ shall produce "eevee".

#include <stdio.h>

void interchangeCase(char phrase[],char c){

  for(int i=0;phrase[i]!='\0';i++){

      if(phrase[i]==c){

          if(phrase[i]>='A' && phrase[i]<='Z')

              phrase[i]+=32;

          else

              phrase[i]-=32;      

      }

  }

}

int main(){

  char c1[]="Eevee";

  interchangeCase(c1,'e');

  printf("%s\n",c1);

  char c2[]="Eevee";

  interchangeCase(c2,'E');

  printf("%s\n",c2);    

}
