Thread: My Program Won't Display First Few Data...

hey guys, can you please help me out with my project? i made a program that would ask the user to input names, which the program would then arrange alphabetically. Then the program would ask for quiz grades, project grade, and final examination grade. The program then would compute for the raw score and display the corresponding mark (4.0 = 95 to 100, 3.5 = 90 - 95, etc.)

The problem is that, my program displays the grades properly, but the first few names aren't displayed. i don't see anything wrong with my program but i'm sure there is. Please do reply to my post! any help would be appreciated.

Code:

#include<iostream.h>
#include<stdio.h>
#include<iomanip.h>

struct records
{
float quiz_1;
float quiz_2;
float quiz_3;
float proj;
float finals;
float raw;
float final_grade;
};

main()
{
FILE *fp;
fp=fopen("C:\\Users\\User\\Documents\\ClassDataBase.txt","w");
{
records *rec;
char *name[50], temp[50];
int m, n, x;
rec=new records[x];

printf("@@@@@\t@@@@@\t@@@@@@@@@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@@@@@@@@@\n@@@@@\t@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@\t\t@@@@@\t@@@@@\n@@@@@@@@@@@@@\t@@@@@@@@@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@\t@@@@@\n@@@@@\t@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@\t\t@@@@@\t@@@@@\n@@@@@\t@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@\t\t@@@@@\t@@@@@\n@@@@@\t@@@@@\t@@@@@@@@@@@@@\t@@@@@@@@@@@@@\t@@@@@@@@@@@@@\t@@@@@@@@@@@@@\n\n");
fprintf(fp,"@@@@@\t@@@@@\t@@@@@@@@@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@@@@@@@@@\n@@@@@\t@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@\t\t@@@@@\t@@@@@\n@@@@@@@@@@@@@\t@@@@@@@@@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@\t@@@@@\n@@@@@\t@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@\t\t@@@@@\t@@@@@\n@@@@@\t@@@@@\t@@@@@\t\t@@@@@\t\t@@@@@\t\t@@@@@\t@@@@@\n@@@@@\t@@@@@\t@@@@@@@@@@@@@\t@@@@@@@@@@@@@\t@@@@@@@@@@@@@\t@@@@@@@@@@@@@\n\n");
printf("How many records would you like to enter?");
scanf("%d",&x);
for (m=0;m<x;m++)
{
printf("\nEnter name: ");
name[m] = (char *) malloc (50);
scanf("%s",name[m]);
}
 for (m = 0; m <= x; m++)
{
for (n = 1; n <= x-m; n++)
if (strcmp(name[n - 1], name[n]) > 0)
{
strcpy(temp, name[n - 1]);
strcpy(name[n - 1], name[n]);
strcpy(name[n], temp);
temp[0] = '\0';
}
}

 for(m=0;m<x;m++)
 { 
   printf("\n\nInput Grades For %s\n",name[m]);
   printf("   Quiz 1: ");
   scanf("%f",&rec[m].quiz_1);
   printf("   Quiz 2: ");
   scanf("%f",&rec[m].quiz_2);
   printf("   Quiz 3: ");
   scanf("%f",&rec[m].quiz_3);
   printf("   Project: ");
   scanf("%f",&rec[m].proj);
   printf("   Finals: ");
   scanf("%f",&rec[m].finals);
   rec[m].raw=((((rec[m].quiz_1)+(rec[m].quiz_2)+(rec[m].quiz_3))/3)*0.40)+((rec[m].proj)*0.20)+((rec[m].finals)*0.40);
 
 if(rec[m].raw<60)
 {
 rec[m].final_grade=0;
 }
 if(rec[m].raw>=60&&rec[m].raw<65)
 {
 rec[m].final_grade=1;
 }
 if(rec[m].raw>=65&&rec[m].raw<70)
 {
 rec[m].final_grade=1.5;
 }
 if(rec[m].raw>=70&&rec[m].raw<75)
 {
 rec[m].final_grade=2.0;
}
if(rec[m].raw>=75&&rec[m].raw<85)
 {
 rec[m].final_grade=2.5;
}
if(rec[m].raw>=85&&rec[m].raw<90)
 {
 rec[m].final_grade=3.0;
}
if(rec[m].raw>=90&&rec[m].raw<95)
 {
 rec[m].final_grade=3.5;
}
if(rec[m].raw>=95)
 {
 rec[m].final_grade=4.0;
}
}


printf("----------RECORDS----------\n\n");
fprintf(fp,"----------RECORDS----------\n\n");
printf("Name\t\tQuiz 1\tQuiz 2\tQuiz 3\tProject\tFinals\tRaw\tFinal Grade\n"); 
fprintf(fp,"Name\t\tQuiz 1\tQuiz 2\tQuiz 3\tProject\tFinals\tRaw\tFinal Grade\n"); 
 for (m=0; m<x; m++)
{
printf("%s\t%.2f\t%.2f\t%.2f\t%.2f\t%.2f\t%.2f\t%.2f\n\n", name[m],rec[m].quiz_1,rec[m].quiz_2,rec[m].quiz_3,rec[m].proj,rec[m].finals,rec[m].raw,rec[m].final_grade);
fprintf(fp,"%s\t%.2f\t%.2f\t%.2f\t%.2f\t%.2f\t%.2f\t%.2f\n\n", name[m],rec[m].quiz_1,rec[m].quiz_2,rec[m].quiz_3,rec[m].proj,rec[m].finals,rec[m].raw,rec[m].final_grade);
}
fclose(fp);
system("pause");
}
}

Output should be something like this:

----------RECORDS----------

Name Quiz 1 Quiz 2 Quiz 3 Project Finals Raw Final Grade
Lee,Bruce.K. 96.00 94.00 95.00 96.00 94.00 94.80 3.50

Smith,John.C. 95.00 99.00 994.00 94.00 99.00 216.80 4.00

Tan,Mike.J. 59.00 96.00 95.00 94.00 89.00 87.73 3.00


Instead, it shows*:

----------RECORDS----------

Name Quiz 1 Quiz 2 Quiz 3 Project Finals Raw Final Grade
96.00 94.00 95.00 96.00 94.00 94.80 3.50

Smith,John.C. 95.00 99.00 994.00 94.00 99.00 216.80 4.00

Tan,Mike.J. 59.00 96.00 95.00 94.00 89.00 87.73 3.00

*not displaying Lee,Bruce.K.

Not sure how it even runs.

Code:

int m, n, x;
rec=new records[x];
