For help, please help me have a look at where is wrong-CodePudding

CodePudding user response:

ReadScore I there is initialized

CodePudding user response:

And an array of ReadScore [I] is not defined, you should be income [I] have the wrong number.
And a function under the num=x [I] what is the fairy

CodePudding user response:

Int ReadScore (int income [], long num [])
{
Int I =0 ;
Do {
i++;
Printf (" Input the person 's ID and income: ");
The scanf (" % d % ld ", & amp; Num [I], & amp; Income [I]);
} while ( I num [I] & gt; 0/* & amp; & ReadScore [I] & gt;=0 */);
//ReadScore [I] don't have the array, don't know what you want to express
return i;
//this I still could be out from while the condition of N, then return to this I should not be, or have potential risks
}

Int LinSearch (long num [], long x, int n)
{
Int I;
for (i=0; i<=n; I++)
{
If (num [I] == x) return (I);
