I want to have the second line of code to have the user input the Fahrenheit not the Celsius twice. The int main() code is correct and the output number is correct but the user does not input the Fahrenheit. How do I fix this? enter image description here
What is expected is that the user inputs the Fahrenheit and the code continues. I do not want the output to skip over lines 12-14. I don't know how to fix this. I expect that once the user inputs Fahrenheit the code will continue to run as it currently does
#include <stdio.h>
#include <math.h>
double ask_for_air_celcius()
{
double temp_celcius, temp;
printf("Enter the current air temperature(in Celcius): ");
scanf(" %lf", &temp_celcius);
return(temp_celcius);
printf("Enter the current air temperature(in Fahrenheit): ");
scanf(" %lf", &temp);
return (temp);
}
int main()
{
double temp_celcius, spsound_1,spsound_convert_1,temp,
spsound,spsound_convert;
{
temp_celcius = ask_for_air_celcius();
spsound_1 = 1086 * sqrt(((5 * (temp_celcius*1.8+32)) + 297)
/ 247);
spsound_convert_1=spsound_1*1.09728;
temp = ask_for_air_celcius();
spsound = 1086 * sqrt(((5 * temp) + 297) / 247);
spsound_convert=spsound*1.09728;
printf("\nThe speed of sound at %.2f degrees Celcius is %.2f
ft/s.\n", temp_celcius, spsound_1);
printf ("The speed of sound at this temperature in Celciusis
equivalent to %.2f km/h.\n\n", spsound_convert_1);
printf("The speed of sound at %.2f degrees Fahrenheit is %.2f
ft/sec.\n", temp, spsound);
printf ("The speed of sound at this temperature in Fahrenheit
is equivalent to %.2f km/h.\n", spsound_convert);
}
return(0);
}
You used used return
twice in the function so that it won't go ahead
for asking the fahrenhiet question. Whenever return
is encountered while compiling it terminates the function there and there only.
Now what you can do is that just make another function
for fahrenhiet and copy paste the fahrenhit part in it.
#include <stdio.h>
#include <math.h>
double ask_for_air_celcius(){
double temp_celcius;
printf("Enter the current air temperature(in Celcius): ");
scanf(" %lf", &temp_celcius);
return(temp_celcius);
}
double ask_for_air_Fahrenhiet(){
double temp;
printf("Enter the current air temperature(in Fahrenheit): ");
scanf(" %lf", &temp);
return (temp);
}
int main()
{
double temp_celcius, spsound_1,spsound_convert_1,temp,
spsound,spsound_convert;
{
temp_celcius = ask_for_air_celcius();
spsound_1 = 1086 * sqrt(((5 * (temp_celcius*1.8+32)) + 297)
/ 247);
spsound_convert_1=spsound_1*1.09728;
temp = ask_for_air_Fahrenhiet();//changes here
spsound = 1086 * sqrt(((5 * temp) + 297) / 247);
spsound_convert=spsound*1.09728;
printf("\nThe speed of sound at %.2f degrees Celcius is %.2f ft/s.\n", temp_celcius, spsound_1);
printf ("The speed of sound at this temperature in Celciusis equivalent to %.2f km/h.\n\n", spsound_convert_1);
printf("The speed of sound at %.2f degrees Fahrenheit is %.2f ft/sec.\n", temp, spsound);
printf ("The speed of sound at this temperature in Fahrenheit is equivalent to %.2f km/h.\n", spsound_convert);
}
return(0);
}
Hope it helps;!! ;)
