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;
}
Solution
#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;
}
