Question

[10 marks] (b) The diagram below shows part of a structure chart for the design of an "intelligent washing machine which varies washing time with the characteristics of the washing load. Main Weight Dirt Level Washing Grease ||' Time Level Calculate Washing Time Washing Time = (1+Weight)(Dirt Level)x(Grease Level)2 Write a C function called CalculateWashing Time which takes floating point values Weight, Dirt Level and Grease Level as input parameters and returns the floating point value of the Washing Time. You should take care to ensure that the syntax of your C function, including parameters, is correct. [10 ma UFMFN7-15-1 Page

Answer 1

C function called CalculateWashingTime is as follows:

float CalculateWashingTime(float weight,float dirt_level,float grease_level)
{
float washing_time;
washing_time = (1+weight)*(dirt_level)*((grease_level)*(grease_level));
return washing_time;
}

Complete C program to calculate washing time is as follows:

#include <stdio.h>

float CalculateWashingTime(float ,float ,float );//function declaration

int main(){
float a;
a = CalculateWashingTime(9,10,10);// function call
printf("%f",a);
}

// function definition
float CalculateWashingTime(float weight,float dirt_level,float grease_level)
{
float washing_time;
washing_time = (1+weight)*(dirt_level)*((grease_level)*(grease_level));
return washing_time;
}

main.c #include <stdio.h> float CalculateWashingtime(float ,float ,float ); / 5. int main() { float a; a = CalculateWashingTime(9,10,10); printf("Washing time for given weight, dirt_level and grease_level is %f",a); 10 float CalculateWashingTime(float weight, float dirt_level,float grease_level), float washing_time; washing_time = (1+weight)*(dirt_level)*((grease_level)*(grease_level)); 14 //printf("%f", washing_time); return washing_time; 26 17 } input Washing time for given weight, dirt_level and grease_level is 10000.000000
