How to remove any character from string in c

 In this I will tell you how to remove any character from the given String in C . So without any further delay let's get started .

Code:

#include<stdio.h>

#include<string.h>

//how to remove any character from string in c

int main(){

    char str[100];

printf("Enter the string \n");

    scanf("%[^\n]s",str);

  int j = 0;

    for(int i=0;str[i]!='\0';i++){

           if (str[i] == 'a')

        {

         str[j++]=str[i+1];  

         i++; 

        }

        else{

         str[j++]=str[i];

        }

        

    }

str[j]='\0';

    printf("%s  ",str);

    return 0;

}

Logic:

Now that we have see the code let's understand one by one . First of all we created a String of length 100 . And named it str . Then with the help of printf function we print user message to Enter the string . And then with help of scanf function  taking  String  as input. From the user .  And then we use a for loop and  run it till the end of the String. And we also declare variable j and initialize it from 0. For indexing of the same String after that character is removed . Then we take use   if-else  and in if condition we check for str[i]== 'a' if found then character after that is copied  in str[j++] else it copy before it is copied in str[j++]=str[i]  . And then after doing all this we end the String with '\0'.

Output:

And here you can see that our program work correctly and remove character 'a' from the String . Try this program by yourself and please provide me feedback by commenting your opinion . I hope that you find this helpful in your work.

School fee management program using C language

 In this I will let you know how to write a program that manage school without using any complication . So , without wasting our let's get started .  First I show you code then we come to explanation .

Code:

#include <stdio.h>

//School fees management program using C languag

int main()

{

    //For Students Details

    char SchoolName[30];//School Name

    char Date[10];//To get date 

    int Eno;        //Student Enrollement

    char Sname[20]; //Student Name

    char Fname[20]; //Student's Father's Name

    char Mname[20]; //Student's Mother's Name

    char C_S[10];   //Class and Section

    //Now for fees details

    int CMF; //Consoliated Monthly fees

    int R_f; //Readmission and fine

    int Conveyance;//If you use bus 

    int Tfess;//Term fees 

    int Cfess;//Computer fees

    int Exam;//Exam fees

    int Rfess;//Registration fees

    int Afess;//Admission fees 

    int concession;//Concession fees 

    int grTotal;//grand Total

    printf("Enrollenment no.\n");

    scanf("%d",&Eno);

    printf("School name\n");

    scanf(" %[^\n]s",SchoolName);

    printf("Date\n");

    scanf(" %[^\n]s",Date);

    printf("Student name\n");

    scanf(" %[^\n]s",Sname);

    printf("Father's Name\n");

    scanf(" %[^\n]s",Fname);

    printf("Mother's Name\n");

    scanf(" %[^\n]s",Mname);

    printf("Class & section\n");

    scanf(" %[^\n]s",C_S);

    printf("Consilated Monthly Fees:\n");

    scanf("%d",&CMF);

    printf("Readmission/Fine: \n");

    scanf("%d",&R_f);

    printf("Conveyance: \n");

    scanf("%d",&Conveyance);

    printf("Term Fees: \n");

    scanf("%d",&Tfess);

    printf("Computer fees: \n");

    scanf("%d",&Cfess);

    printf("Exam fees: \n");

    scanf("%d",&Exam);

    printf("Registration Fees: \n");

    scanf("%d",&Rfess);

    printf("Admission Fees :\n");

    scanf("%d",&Afess);

    printf("Concession: \n");

    scanf("%d",&concession);

    grTotal=(CMF+R_f+Conveyance+Tfess+Cfess+Exam+Rfess+Afess)-(concession);

    //Grandtotal is sum of all subract concession 

     printf("Date:%s     School Name :%s\n",Date,SchoolName);

     printf("Enrollement No.%d         Student Name:%s   Class & Section: %s\n",Eno,Sname,C_S);

     printf("Father's Name:%s            Mother's Name:%s\n",Fname,Mname);

     printf("------------------------------------------------------------------------------\n");

     printf("Consilated Monthly Fees : %d\t\t Readmission/fine :%d\n",CMF,R_f);

     printf("Conveyance fees :%d\t\t Term Fees : %d\n ",Conveyance,Tfess);

     printf("Computer fees : %d \t\t Exam fees :%d\n",Cfess,Exam);

     printf("Registration fees : %d \t \t Admission fees :%d\n ",Rfess,Afess);

     printf("Concession : %d\n");

     printf("----------------------------------------------------------------------------------\n");

     printf("Grand Total : %d \n",grTotal);

    return 0;

}

Logic:

Here we first declare  the variables for the details of the students . Namely SchoolName , Date, Sname(Student's Name), Fname(father's Name), Mname(mother's Name), C_S(class & section)  of type character array(String) and  Eno(Enrollement No) of type int. And then we  define variables for fees details of the students . I just define variables for only few important fees details you can customize it according to yours . Here two important variables is necessary that is grTotal(grand Total) of fees and Concession . And then we take input to these variables for int data type taking input is easy . And for String  we take input using special method  About input in String . And then we do grandTotal of fees by adding other charges  and subtract concession from it . And then we just use printf statement and to show user  fees summary of student.

Output:

here you can see that we give input as required . And then we get our desired output . This tells us that our program work properly. Try this by self by changing the variables . Please provide feedback  this code by commenting  your views.  I hope this is helpful in your work . Thanks for reading.
