write a c program to convert temperature(Celsius to Fahrenheit) and vice verse

#include <stdio.h>
main()
{
    float fh,cl;
    int choice;
    printf("n1: Convert temperature from Fahrenheit to Celsius."); 
    printf("n2: Convert temperature from Celsius to Fahrenheit.");
    printf("nEnter your choice (1, 2): ");
    scanf("%d",&choice);
    if(choice ==1){
        printf("nEnter temperature in Fahrenheit: ");
        scanf("%f",&fh);
        cl= (fh - 32) / 1.8;
        printf("Temperature in Celsius: %.2f",cl);
    }
    else if(choice==2){
        printf("nEnter temperature in Celsius: ");
        scanf("%f",&cl);
        fh= (cl*1.8)+32;
        printf("Temperature in Fahrenheit: %.2f",fh);
    }
    else{

       printf("nInvalid Choice !!!");
    }
getch();
}
