The meaning of these warnings. C language

[mrgenousprogram]

Hi,

I just started studying C programming and I began to make a console program project. I am using code block for my compiler. Looks like every time I use if statement, this warning always come

|warning: assignment to 'int' from 'char *' makes integer from pointer without a cast [-Wint-conversion]

warning: suggest parentheses around assignment used as truth value [-Wparentheses]|

All I want to know is what are these warnings meaning.

The warnings exactly mean what the text says. Show your code.

So, is there anything I can do to fix this or I don't need to do anything?

[dev7060]

Potential issues are indicated by warnings. Warnings would not prevent the code from being compiled. To produce a robust thing, warnings should never be ignored.

So, is there anything I can do to fix this or I don't need to do anything?

I can't suggest the fix if I don't know in the first place what is there to apply the fix to.

These are the codes that got warned

if (menu_pitagoras = "1")

if (menu = "1")

all the codes that are contained within the if statement got neither warnings nor errors

these are the codes inside the if statement

if (menu = "1")
    {
        printf ("\n1. Alas\n2. Tinggi\n3. Diagonal\nPilih sisi:");
        scanf ("%d", &menu_pitagoras);
 
        if (menu_pitagoras = "1")
        {
            printf ("\nTinggi:");
            scanf ("%f", &tinggi);
            printf ("\nDiagonal:");
            scanf ("%f", &diagonal);
 
            pitagoras_alas = sqrt (tinggi*tinggi+diagonal*diagonal);
 
            printf ("\nHasil:%f", pitagoras_alas);
            }

just in case if these codes needed to be checked

[dev7060]

Use strcmp() for strings (represented as char arrays in C) and use comparison operator instead of assignment one for integer values.

[mrgenousprogram]

Ummm, can you please give an example?

[dev7060]

If the vars are declared as int,

if (menu == 1)
 

if (menu_pitagoras == 1)
 

For string comparison,

if(strcmp(menu, "1")==0)

Excellent, you're my project savior. I can finally continue my project
