CORRECT THIS C PROGRAM FOR ME PLEASE.
Suppose that at a particular steel mill, steel bars are grouped into classes according to their yield tensile strength as shown in the following table (note that this is not a standard classification):
Class Tensile strength (MPa)
-------------------------------------------------
A 1000.0 <= strength
B 800.0 <= strength < 1000.0
C 600.0 <= strength < 800.0
D 400.0 <= strength < 600.0
E strength < 400.0
Write a program which reads a yield tensile strength from the file steelclassin.txt, calls the function class to determine the corresponding class and then the main program writes the strength and corresponding class to a file steelclassout.txt. This continues until the end of the input file is reached. Your output file should look like:
Tensile Strength Class
----------------------------
649.4 C
827.3 B
989.7 B
453.6 D
278.3 E
THIS IS MY OUTPUT:
Tensile Strength Class
----------------------------
827.3 B
989.7 B
453.6 D
278.3 E
IT won't print the first number and I don't know why.
Here's my code:
#include<stdio.h>
char class(float strength);
int main(void){
float strength;
char answer;
FILE * fin = fopen("steelclassin.txt", "r");
FILE * fout = fopen("steelclassout.txt", "w");
fscanf(fin, "%f", &strength);
fprintf(fout, " Tensile Strength Class ");
fprintf(fout, "---------------------------- ");
while(fscanf(fin, "%f", &strength)!=EOF){
answer = class(strength);
fprintf(fout, "%.1f %c ", strength, answer);
}
fclose(fin);
fclose(fout);
system("notepad.exe steelclassout.txt");
return 0;
}
char class(float strength){
char answer;
if(strength >= 1000.0){
answer = 'A';
}else if(strength >= 800.0){
answer = 'B';
}else if(strength >= 600.0){
answer = 'C';
}else if(strength >= 400.0){
answer = 'D';
}else{
answer = 'E';
}
return answer;
}
Explanation / Answer
#include<stdio.h>
char class(float strength);
int main(void){
float strength;
char answer;
FILE * fin = fopen("steelclassin.txt", "r");
FILE * fout = fopen("steelclassout.txt", "w");
//
//fscanf(fin, "%f", &strength);
fprintf(fout, " Tensile Strength Class ");
fprintf(fout, "---------------------------- ");
//We are reading values from the file.
while(fscanf(fin, "%f", &strength)!=EOF){
answer = class(strength);
fprintf(fout, "%.1f %c ", strength, answer);
}
fclose(fin);
fclose(fout);
system("notepad.exe steelclassout.txt");
return 0;
}
char class(float strength){
char answer;
if(strength >= 1000.0){
answer = 'A';
}else if(strength >= 800.0){
answer = 'B';
}else if(strength >= 600.0){
answer = 'C';
}else if(strength >= 400.0){
answer = 'D';
}else{
answer = 'E';
}
return answer;
