Thread: How Can I test for characters in in char variable and multiply floats

Just a to let you know, I began learning C few days ago so I only know some syntax. Anyways, here is the problem. I dont know if, if(char var == 'character') is wrong or is there different way to multiply different floats? Thank you in advance

Code:

#include <stdio.h>
#include <stdlib.h>
#define offroad 2.2
#define motorway 1.3


int main()
{


    float way1;
    float mile1;
    float way2;
    float mile2;
    float way3;
    float mile3;
    char answer1 [2];
    char answer2 [2];
    char answer3 [2];


//Ask options to calculate results
    printf("Please enter the information in order to obtain your results\n");


    printf("Will the road be a motorway(m) or offroad (o)?\n");
    scanf(" %c", answer1);
    printf("What distance in KM will you cover?\n");
    scanf(" %f", &way1);


    printf("Will the road be a motorway(m) or offroad (o)?\n");
    scanf(" %c", answer2);
    printf("What distance in KM will you cover?\n");
    scanf(" %f", &way2);


    printf("Will the road be a motorway(m) or offroad (o)?\n");
    scanf(" %c", answer3);
    printf("What distance in KM will you cover?\n");
    scanf(" %f", &way3);


    mile1 = way1;
    mile2 = way2;
    mile3 = way3;


// Here is my problem way1 = way1 * motorway etc. doesnt work or the "if(answer1 == 'm')" statement is wrong.

    if(answer1 == 'm'){
        way1 *= motorway;
    }
    if(answer1 == 'o'){
        way1 *= offroad;
    }
    if(answer2 == 'm'){
        way2 *= motorway;
    }
    if(answer2 == 'o'){
        way2 *= offroad;
    }
    if(answer3 == 'm'){
        way3 *= motorway;
    }
    if(answer3 == 'o'){
        way3 *= offroad;
    }
//Convert way variables into miles
    mile1 *= 1.6;
    mile2 *= 1.6;
    mile3 *= 1.6;


    printf("Trip 1 will be %.3f miles and use %.3f liters of fuel\n", mile1, way1);
    printf("Trip 2 will be %.3f miles and use %.3f liters of fuel\n", mile2, way2);
    printf("Trip 3 will be %.3f miles and use %.3f liters of fuel\n", mile3, way3);


    return 0;
}
