#include <stdio.h>
struct student
{
int id;
float hr;
float hours;
float wage;
};
struct student data[6], data1[6];
FILE *fptr;
void shortData(int opt) {
int i,j;
struct student temp;
if(opt == 2) {
for (i = 0; i < 6; ++i)
{
for (j = i + 1; j < 6; ++j)
{
if (data[i].id > data[j].id)
{
temp = data[i];
data[i] = data[j];
data[j] = temp;
}
}
}
} else if(opt == 3) {
for (i = 0; i < 3; ++i)
{
for (j = i + 1; j < 3; ++j)
{
if (data[i].hr > data[j].hr)
{
temp = data[i];
data[i] = data[j];
data[j] = temp;
}
}
}
} else if(opt == 4) {
for (i = 0; i < 3; ++i)
{
for (j = i + 1; j < 3; ++j)
{
if (data[i].hours > data[j].hours)
{
temp = data[i];
data[i] = data[j];
data[j] = temp;
}
}
}
} else if(opt == 5) {
for (i = 0; i < 3; ++i)
{
for (j = i + 1; j < 3; ++j)
{
if (data[i].wage > data[j].wage)
{
temp = data[i];
data[i] = data[j];
data[j] = temp;
}
}
}
}
}
int main(void) {
int i=0, opt;
fptr = fopen("std.txt", "w+");
if(fptr == NULL) {
printf("file open failed");
return 0;
}
printf("Enter student details: ");
for(i=0; i<6; i++) {
scanf(" %d %f %f %f", &data[i].id, &data[i].hr, &data[i].hours, &data[i].wage);
fprintf(fptr, "%d %f %f %f ", data[i].id, data[i].hr, data[i].hours, data[i].wage);
}
rewind(fptr);
printf("read from file: ");
for(i=0; i<6;i++) {
fscanf(fptr, "%d %f %f %f", &data1[i].id, &data1[i].hr, &data1[i].hours, &data1[i].wage);
printf("%d %f %f %f ", data1[i].id, data1[i].hr, data1[i].hours, data1[i].wage);
}
printf("Enter your option --> ");
scanf("%d", &opt);
if(opt >= 6){
return 0;
}
if(opt != 1)
shortData(opt);
printf("ID Hourly rate hours Wage ");
for(i=0; i<6;i++) {
printf("%d %f %f %f ", data[i].id, data[i].hr, data[i].hours, data[i].wage);
}
return 0;
}
output will display like below example:
Enter your option --> 1
