Hello,

I'm not sure why but the program won't let me enter a character:

#include<stdio.h>
#include<stdlib.h>

#define EG 0.23
#define AG 0.70
#define TG 0.15

 main(){
	

	
	int posothta;
	char eidos;
	float poso;
	
	
	
	printf("Dwse posothta grammatosimwn: ");
	scanf("%d",&posothta);
	printf("Dwse to eidos grammatoshmou: ");
	scanf("%c",&eidos);
	
	if(eidos=='E' || eidos=='e'){
		poso=posothta*EG;
		printf("To poso pou plirwnoume einai: %f",poso);
	}else if(eidos=='A' || eidos=='a'){
		poso=posothta*AG;
		printf("To poso pou plirwnoume einai: %f",poso);
	}else if(eidos=='T' || eidos=='t'){
		poso=posothta*TG;
		printf("To poso pou plirwnoume einai: %f",poso);
	}else{
		printf("Kapou exei gine kapoio la9os");
	}	
	
 
	return 0;
	
	
}

Fixed, you needed to use fflush to empty the buffer since the "\n" character was left in the buffer after getting the input for posothta and the "\n" character was being taking as the input for the char variable eidos.

 

#include <stdio.h>
#include <stdlib.h>


#define EG 0.23
#define AG 0.70
#define TG 0.15


int main(){

    int posothta;
    char eidos;
    float poso;

    printf("Dwse posothta grammatosimwn: ");
    scanf("%d", &posothta);
    fflush(stdin);
    printf("Dwse to eidos grammatoshmou: ");
    scanf("%c",&eidos);

    if(eidos=='E' || eidos=='e'){
        poso=posothta*EG;
        printf("To poso pou plirwnoume einai: %f",poso);
    }else if(eidos=='A' || eidos=='a'){
        poso=posothta*AG;
        printf("To poso pou plirwnoume einai: %f",poso);
    }else if(eidos=='T' || eidos=='t'){
        poso=posothta*TG;
        printf("To poso pou plirwnoume einai: %f",poso);
    }else{
        printf("Kapou exei gine kapoio la9os");
    }

    return 0;
}

Make sure next time that you enter your code correctly into your posts
