Hello! !
one of the mistakes of the program is that it was entered with a space, and the program changed one place
the modified complete code: # include <; stdio.h>
main()
{
? float? chc,chf,cha;
? char? chb;
? Printf ("Please enter an example according to the specification: 122.12? c\n");
? scanf("%f? %c",& cha,& chb);
? if(chb=='c')
{
? chf=cha/(5./9)+32;
? Printf ("Current Fahrenheit is %.2f%c\n",chf,chb);
?
? }
? else
? {
? chc=(5./9)*(cha-32);
printf ("the current temperature is %.2f%c\n",chc,chb);
? }
}
