My algorithm needs to sum all values between a and b , for example if I type a=3 e b=6 the program needs to speak 3 7 12 18 (3+4= 7/ 7+5=12 / 12+6=18) only it only makes the first two then it starts to err.

#include <stdio.h>  

int main ()  
{  

int a,b,i,n,x,c;  

  printf("Digite a: ");  
  scanf("%d", &a);  
  printf("Digite b: ");  
  scanf("%d", &b);  

  c=0;  
  for(i=1;i<=b;i++)  
  {  
    c=a;  
    a=c+(a+1);  

    printf("%d\n ",c);  

  }


    return 0;  
}

c c++

#include <stdio.h>

int main()
{
    int a, b, soma=0, i;

    printf("Digite a: ");
    scanf("%d", &a);
    printf("Digite b: ");
    scanf("%d", &b);

    for(i=0; i<=b; i++)
    {
        if(i >= a)
        {
            soma = soma + i;
        }
    }
    printf("%i\n", soma);
}

The code is a bit confusing and tries to do too many things. Just start the loop with the first data entered and end with the second. The term is correct, but must start with a .

#include <stdio.h>  

int main() {
    int a, b;
    printf("Digite a: ");
    scanf("%d", &a);
    printf("Digite b: ");
    scanf("%d", &b);
    int soma = 0;
    for (int i = a; i <= b; i++) {
        soma += i;
        printf("%d ", soma);
    }
}
