BCA PRACTICAL SLIPS SOLUTION

Slip 3
Q1. Write a C program to accept temperatures in Fahrenheit (F) and display it in Celsius(C)
and Kelvin (K) (Hint: C=5.0/9(F-32), K = C + 273.15) [15 Marks]
#include<stdio.h>
#include<conio.h>
int main()
{
float cel,fer,kel;
printf("Enter Temperature in Fahrenheit :");
scanf("%f",&fer);
cel= (fer-32)/1.8 ;
printf("Celsius = %f \n",cel);
kel = (fer-32)/1.8 + 273.15 ;
printf("Kelvin = %f \n",kel);
return (0) ;
}

Q2. Write a menu driven program to perform the following operations on strings using standard
library functions: [25 Marks]
Length of String 2. Copy String 3. Connect Two Strings 4. Compare two strings
