I have a problem with scanf and giving input a char array with a for loop?

fixed the issue. Will look into that further Your scanf function is catching a carriage return (see Jonathan Leffler comment), using getchar() can solve this, like so:
code :
#include<stdio.h> 

int main(){ 
    int i; char a[100]; 
    for(i = 0; i < 5; i++){    
        printf("print char\n");  
        scanf("%c",&a[i]);   
        getchar(); 
    } 
    a[i] = '\0';
    for(int i = 0; i < 5; i++){
        printf("%c", a[i]);
    }
}

How to use scanf for a char array input?


By : Malcolm Shore

this one helps. The scanf() with format specifier %s scans the input until a space is encountered. In your case, what you are seeing is undefined behavior. Your array can hold 10 chars, but you are writing out of its boundaries.
While you are getting an expected answer now, this is not always guarnateed and may instead cause a crash.

How to use scanf in a loop to get a char* array in c

may help you . This is because a '\n' is left in the buffer when you do scanf() for f_l.
Use a trailing space, it should work
code :
for(i=0 ; i<=f_l ; i++) {
    scanf(" %c", &first[i]);
}

I can not input the names into the char array using scanf

Hope this helps I can not use scanf to enter a name in stdnames array. when compiled it had no error , but as soon as i enter a name and then press enter to write the other name it gives an error and shuts the program. How should I go about it ? , By
code :
char *stdnames[100];
stdnames[count]=malloc(100*sizeof(char)); // You may replace 100 with desired size
stdnames[count]=malloc(100); // sizeof(char) is almost always 1
free(stdnames[count]);

hope this fix your issue For a start it should be int main...
Also you need to check the return value from scanf - please read the manual page.
code :
#include <stdlib.h>
#include <stdio.h>
int main()
{
    char character;

    while (scanf("%c", &character) == 1) {
       if (character != '\n) {
         printf("%c", character)
       }
    }
    return EXIT_SUCCESS;
}

scanf replaces last elements in char array with the next scanf input

like below fixes the issue You are passing a char** to both printf and scanf. The %ss expect char*s, not char**s. So, replace the following:
