  1. PONot getting correct variable assignment from getchar in C
    text
    copied!<p>I'm writing a simple calculation program, however the only string handling functions I can use are getchar and putchar. Right now I'm just trying to assign the numbers from input to variables, but when I print the variable it's some random number. For example, I entered 3 into the console and the output was 505110. Any help would be appreciated. Thank you. </p> <pre><code>#include &lt;stdio.h&gt; #include "math.h" int addFunction( int, int); int subtractFunction(int, int); int multiplyFunction(int, int); int modulusFunction(int, int); float divideFunction(float, float); int main(int argc, const char * argv[]) { int iochar = 0; char num1 = 0, num2 = 0, continuePrompt, operator = 0; do { iochar = getchar(); getchar(); if ((iochar &gt;= 0) &amp;&amp; (iochar &lt;= 20000)) { num1 = iochar; } if ((iochar == '+') || (iochar == '-') || (iochar == '*') || (iochar == '/') || ( iochar == '%')) { operator = iochar; } if ((num1 &gt;= 0) || ((iochar &gt;= 0) &amp;&amp; (iochar &lt;= 20000))){ num2 = iochar; } switch (operator) { case '+': iochar = addFunction(num1, num2); break; case '-': iochar = subtractFunction(num1, num2); break; case '*': iochar = multiplyFunction(num1, num2); break; case '%': iochar = modulusFunction(num1, num2); break; case '/': iochar = divideFunction(num1, num2); break; } putchar(iochar); printf("Would you like to make another calulation? (y or n)"); scanf("%c", &amp;continuePrompt); } while (continuePrompt != 'n'); return 0; } int addFunction(int x, int y){ return x + y; } int subtractFunction(int x, int y){ return x - y; } int multiplyFunction(int x, int y){ return x * y; } int modulusFunction(int x, int y){ return x % y; } float divideFunction(float x, float y){ return x / y; } </code></pre>
