Need help with C program Need to use buble sort to sort all

Need help with C program. Need to use buble sort to sort all my friends in ascending order for option 3. please help.

#include <stdio.h>
#include <stdlib.h>

//Struct to hold fraction data
typedef struct fraction
{
   int numerator, denom;
}fraction;

int main()
{
   //Array of 100 fractions
   fraction arrFraction[100];

   int i = 0;
       int j;
       int num = 1;
  
   while (num == 1)
   {
       int choice;
       printf(\"\ Press 1 to enter a fraction\ \");
       printf(\"Press 2 to view stored fractions\ \");
       printf(\"Press 3 to sort fractions\ \");
       scanf(\"%d\", &choice);

       if(choice == 1)
       {
           //Prompting user
           printf(\"\ Enter your fraction, numerator followed by denominator\ \");

           //Reading values from user
           scanf(\"%d %d\", &arrFraction[i].numerator, &arrFraction[i].denom);

           //Incrementing counter
           i++;
  
       }

       if (choice == 2) {
           printf(\"-------------------------\ \");
           for (j = 0; j < i; j++)
              
           {
               printf(\"%d %d/%d \ \", arrFraction[j].numerator/arrFraction[j].denom, arrFraction[j].numerator%arrFraction[j].denom, arrFraction[j].denom);
           }
           printf(\"\ -------------------------\ \ \");
       }
      
  
      
       if (choice == 3)
       {
      

       }
  
  
  
  
   }

   system(\"pause\");
   return(0);
}

//Prompting user
printf(\"\ Enter your fraction, numerator followed by denominator\ \");
//Reading values from user
scanf(\"%d %d\", &arrFraction[i].numerator, &arrFraction[i].denom);
//Incrementing counter
i++;
  
}
else if (choice == 2) {
printf(\"-------------------------\ \");
for (j = 0; j < i; j++)
  
{
printf(\"%f %d/%d \ \", (float)arrFraction[j].numerator/arrFraction[j].denom, arrFraction[j].numerator%arrFraction[j].denom, arrFraction[j].denom);
}

}
  
  
  
else if (choice == 3)
