Question

using C language

Create an array of doubles with 5 elements. In the array prompt the user to enter 5 temperature values (in degree Fahrenheit). Do this within main. Create a user defined function called convert2Cels. This function will not return any values to main with a return statement. It should have parameters that include the temperature array and the number of elements. The function should convert the values for Fahrenheit to Celsius and save them back into the same array Celsius = (F - 32) From main, print the modified temperature array in a single column format similar to one shown below. Temperatures(Celsius) 37.78 65.56 100.00 0.00 21.11 Test your program with the following values 100 150 212 32 70

Answer 1

#include <stdio.h> 2 #include<math.h> 3 void convert2cel(double [],int x); 4 int main() double temp_array[5]; int i,n=5; printf("Enter a fahrenherit values:\n"); for(i=0;i<n;i++) { scanf("%lf",&temp_array[i]); 10 / *here we take fahrenherit tem from user */ 11 12 13 convert2cel(&temp_array,n); /*here we call convert2cel function for Convert temp to celsius*/ 14 15 printf("\nTemperatures(Celsius):\n"); for(i=0;i<n;i++) { printf("%.21f \n",temp_array[i]); 16 /*here we print celsius temp*/ 17 18 19 20 21 return 0; 22 } 23 24 void convert2cel(double temp_array[],int n) 25 - { /*in this function we convert fahrenherit to celsius*/ int i; double cal=0,fahrenherit; for(i=0;i<n;i++) 26 27 /*here we do for 5 times to convert 5 temp into celsius*/ 28 29 cal=5 * (temp_array[i]-32) / 9; temp_array[i]=cal; 30 31 32 33 34 } 35

output:

Enter a fahrenherit values: 100 150 212 32 70 Temperatures (Celsius): 37.78 65.56 100.00 0.00 21.11 ...Program finished with exit code 0 Press ENTER to exit console.

void convert2cel(double temp_array[],int n) /*in this function we convert fahrenherit to celsius*/
