C :

#include<stdio.h>
int main()
{
	float a;
	printf("Pls Input Temperature In C = ");
	scanf("%f",&a);
	printf("Temperature In F = %.2f\n",a*9/5+32);
	return 0;
}

C++ :

#include <iostream>
#include <cstdio>
using namespace std;
int main()
{ int c;
  double f;
  printf("Pls Input Temperature In C = ");
  scanf("%d",&c);
  f=c*1.8+32;
  printf("Temperature In F = %.2lf",f);
  //system("pause");
  return 0;
}

Pascal :

program aa;
var f,c:real;
a,b,d:integer;
begin
 write('Pls Input Temperature In C = ');
 read(c);
 f:=9*c/5+32;
 write('Temperature In F = ',f:0:2);
end.
