Why this code is not printing?

See more:

C

/*Program to print marks of students in ascending order using structure */
#include<stdio.h>
int main()
{
	int n,c,t;
	printf("Enter Total No Of Students\n");
	scanf("%d",&n);
	c=getchar();
	struct student
	{
	char name[100];
	char section;
	int marks[5];
	}s[n];
		
	for(int i=0;i<n;i++)
	{
		printf("Enter Name :");
		gets(s[i].name);
		printf("\n");
		printf("Enter Section :");
		scanf("%c",&s[i].section);
		printf("\n");
		printf("Enter Marks In 5 Subjects \n");
		for(int j=0;j<5;j++)
		{
			scanf("%d",&(s[i].marks[j]));
		}
		c=getchar();
	}
	for(int i=0;i<n;i++)
	{
		for(int k=0;k<5;k++)
		{
			for(int j=0;j<4;j++)
			{
				if(s[i].marks[j]>s[i].marks[j+1])
				{
					t=s[i].marks[j];
					s[i].marks[j]=s[i].marks[j+1];
					s[i].marks[j+1]=t;
				}
			}
		}	
	}
	for(int i=0;i<n;i++)
	{
		printf("\n\nName\tSection\n");
		printf("%s\t%c\t\n",s[i].name,s[i].section);
		printf("Marks In 5 Subjects \n");
		for(int j=0;j<5;j++)
		{
			printf("%d \n",(s[i].marks[j]));
		}
	}			
	return 0;
}

What I have tried:

This code is not printing the output,I want user to enter data of students and marks in 5 subject & the program will sort marks in ascending order and print the data.
